^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) * Fixed up some places where I assumed that a long int could hold

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) * Andrew Farnham <andrewfarnham@uq.net.au> pointed out that the module
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) wouldn't work on older (<2.4.10) kernels due to an unresolved symbol.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) This is bad, since 2.4.9 is still the current RedHat kernel. I added
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) a workaround for this problem (compatibility.h) [WD]

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) * Sergey S. Kostyliov made befs_find_key() use a binary search to find

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) * Fixed bug in befs_find_brun_indirect() that would result in the wrong
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) block being read. It was introduced when adding byteswapping in

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) * Fixed a longstanding bug in befs_find_key() that would result in it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) finding the first key that is a substring of the string it is searching
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) for. For example, this would cause files in the same directory with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) names like file1 and file2 to mysteriously be duplicates of each other
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) (because they have the same inode number). Many thanks to Pavel Roskin

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 105) * Removed notion of btree handle from btree.c. It was unnecessary, as the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 106) linux VFS doesn't allow us to keep any state between calls. Updated

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 109) * Improved handleing of overflow nodes when listing directories.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 110) Now works for overflow nodes hanging off of nodes other than the root

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 140) hanging disk io problem. It turns out you need to have the sync_pages

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 151) the page size in linux, which is 4k i386. Oops. Added a test for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 152) (blocksize > PAGE_SIZE), and refuse to mount in that case. What this
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 153) practically means is that 8k blocksize volumes won't work without a major

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 159) * Made inode allocations use a slab cache

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 162) * Moved the freeing of the private inode section from put_inode() to

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 164) can be called multiple times for each inode struct. [WD]

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 166) * Converted all non vfs-callback functions to use befs_sb_info as the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 167) superblock type, rather than struct super_block. This is for

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 176) Version 0.45 (2001-10-29)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 177) ==========
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 178) * Added functions to get the private superblock and inode structures from
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 179) their enclosing public structures. Switched all references to the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 180) private portions to use them. (many files) [WD]
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 181)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 182) * Made read_super and read_inode allocate the private portions of those
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 183) structures into the generic pointer fields of the public structures
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 184) with kmalloc(). put_super and put_inode free them. This allows us not
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 185) to have to touch the definitions of the public structures in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 186) include/linux/fs.h. Also, befs_inode_info is huge (because of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 187) symlink string). (super.c, inode.c, befs_fs.h) [WD]

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 189) * Fixed a thinko that was corrupting file reads after the first block_run

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 197) * Removed all the Read-Write stuff. I'll redo it when it is time to add

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 206) * Made it an option to use the old non-pagecache befs_file_read() for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 207) testing purposes. (fs/Config.in)

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 209) * Fixed unused variable warnings when compiling without debugging.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 211) * Fixed a bug where the inode and super_block didn't get their blockbits
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 212) fields set (inode.c and super.c).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 213)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 214) * Release patch version 11. AKA befs-driver version 0.4.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 215)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 216) * Thats right. New versioning scheme.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 217) I've done some serious testing on it now (on my box anyhow), and it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 218) seems stable and not outragously slow. Existing features are more-or-less
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 219) correct (see TODO list). But it isn't 1.0 yet. I think 0.4 gives me some
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 220) headroom before the big 1.0.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 224) ==========
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 225) * Fixed date format in this file. Was I smoking crack?
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 226)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 227) * Removed old datastream code from file.c, since it is nolonger used.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 228)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 229) * Generic_read_file() is now used to read regular file data.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 230) It doesn't chew up the buffer cache (it does page io instead), and seems
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 231) to be about as fast (even though it has to look up each file block
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 232) indivdualy). And it knows about doing readahead, which is a major plus.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 233) So it does i/o in much larger chunks. It is the correct linux way. It
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 234) uses befs_get_block() by way of befs_readpage() to find the disk offsets
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 235) of blocks, which in turn calls befs_fpos2brun() in datastream.c to do
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 236) the hard work of finding the disk block number.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 237)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 238) * Changed method of checking for a dirty filesystem in befs_read_super
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 239) (super.c). Now we check to see if log_start and log_end differ. If so,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 240) the journal needs to be replayed, and the filesystem cannot be mounted.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 241)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 242) * Fixed an extra instance of MOD_DEC_USE_COUNT in super.c

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 244) * Fixed a problem with reading the superblock on devices with large sector

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 249) * Fix nasty bug in converting block numbers to struct befs_inode_addr.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 250) Subtle, because the old version was only sometimes wrong.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 314) This fixed the problmem with wrong file sizes from du and others.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 315) The i_blocks field of the inode struct is not the number of blocks for the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 316) inode, it is the number of blocks for the file. Also, i_blksize is not
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 317) necessarily the size of the inode, although in practice it works out.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 318) Changed to blocksize of filesystem.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 321) * Permanently removed code that had been provisionally ifdefed out of befs_fs.h
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 322)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 323) * Since we don't support access time, make that field zero, instead of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 324) copying m_time.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 327) * Added sanity check for inode reading
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 328) Make sure inode we got was the one we asked for.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 332) Local pointers to commonly used structures in inode.c.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 333) Got rid of abominations befs_iaddr2inode() and befs_inode2ino().
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 334) Replaced with single function iaddr2blockno().

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 339) * Fixed the problem with statfs where it would always claim the disk was
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 340) half full, due to improper understanding of the statfs fields.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 347) * Changed the macros in befs_fs.h to inline functions.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 348) More readable. Typesafe. Better

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 350)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 351) * Moved type definitions from befs_fs.h to a new file, befs_fs_types.h
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 352) Because befs_fs_i.h and befs_fs_sb.h were including befs_fs.h for the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 353) typedefs, and they are inlcuded in <linux/fs.h>, which has definitions
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 354) that I want the inline functions in befs_fs.h to be able to see. Nasty
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 355) circularity.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 362) * Added additional consitency checks on mount
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 363) Check block_size agrees with block_shift
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 364) Check flags == BEFS_CLEAN

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 367) * Tell the kernel to only mount befs read-only.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 368) By setting the SB_RDONLY flag in befs_read_super().
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 369) Not that it was possible to write before. But now the kernel won't even try.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 372) * Got rid of kernel warning on mount.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 373) The kernel doesn't like it if you call set_blocksize() on a device when
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 374) you have some of its blocks open. Moved the second set_blocksize() to the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 375) very end of befs_read_super(), after we are done with the disk superblock.
