^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 167) - Added dentry callbacks to allow the dcache to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 168)   operate case insensitive and length ignorant
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 169)   like the affs itself.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 170) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 171) - getblock() didn't update the lastblock field in the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 172)   inode if the fs was not an OFS. This bug only shows
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 173)   up if a file was enlarged via truncate() and there
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 174)   was not enough space.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 175) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 176) - Remove some more superfluous code left over from
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 177)   the old link days ...
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 178) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 179) - Fixed some oversights which were in patch 2.1.78.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 180) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 181) - Fixed a few typos.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 183) Version 3.6
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 184) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 185) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 186) - dentry changes. (Thanks to Jes Sorensen for his help.)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 187) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 188) - Fixed bug in balloc(): Superblock was not set dirty after
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 189)   the bitmap was changed, so the bitmap wasn't sync'd.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 190) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 191) - Fixed nasty bug in find_new_zone(): If the current
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 192)   zone number was zero, the loop didn't terminate,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 193)   causing a solid lock-up.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 194) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 195) - Removed support for old-style directory reads.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 196) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 197) - Fixed bug in add_entry(): When doing a sorted insert,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 198)   the pointer to the next entry in the hash chain wasn't
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 199)   correctly byte-swapped. Since most of the users of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 200)   affs use it on a 68k, they didn't notice. But why did
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 201)   I not find this during my tests?
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 202) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 203) - Fixed some oversights (version wasn't updated on some
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 204)   directory changes).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 205) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 206) - Handling of hard links rewritten. To the VFS
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 207)   they appear now as normal Unix links. They are
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 208)   now resolved only once in lookup(). The backside
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 209)   is that unlink(), rename() and rmdir() have to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 210)   be smart about them, but the result is worth the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 211)   effort. This also led to some code cleanup.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 212) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 213) - Changed name type to unsigned char; the test for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 214)   invalid filenames didn't work correctly.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 215)   (Thanks to Michael Krause for pointing at this.)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 216) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 217) - Changed mapping of executable flag.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 218) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 219) - Changed all network byte-order macros to the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 220)   recommended ones.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 221) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 222) - Added a remount function, so attempts to remount
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 223)   a dircache filesystem or one with errors read/write
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 224)   can be trapped. Previously, ro remounts didn't
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 225)   flush the super block, and rw remounts didn't
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 226)   create allocation zones ...
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 227) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 228) - Call shrink_dcache_parent() in rmdir().
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 229)   (Thanks to Bill Hawes.)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 230) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 231) - Permission checks in unlink().
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 232) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 233) - Allow mounting of volumes with superfluous
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 234)   bitmap pointers read only, also allows them
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 235)   to be remounted read/write.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 236) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 237) - Owner/Group defaults now to the fs user (i.e.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 238)   the one that mounted it) instead of root. This
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 239)   obsoletes the mount options uid and gid.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 240) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 241) - Argument to volume option could overflow the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 242)   name buffer. It is now silently truncated to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 243)   30 characters. (Damn it! This kind of bug
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 244)   is too embarrassing.)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 245) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 246) - Split inode.c into 2 files, the superblock
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 247)   routines desperately wanted their own file.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 248) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 249) - truncate() didn't allocate an extension block
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 250)   cache. If a file was extended by means of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 251)   truncate(), this led to an Oops.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 252) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 253) - fsuser is now checked last.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 255) - rename() will not ignore changes in filename
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 256)   casing any more (though mv(1) still won't allow

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 262) - Extension block caches are now allocated on
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 263)   demand instead of when a file is opened, as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 264)   files can be read and written without opening
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 265)   them (e. g. the loopback device does this).

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 280) - Errors and warnings are now reported via a

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 282)   and have the same appearance:

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 286) - The filesystem is remounted read-only after an

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 296) - Extension block cache: Reading/writing of huge files
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 297)   (several MB) is much faster (of course the added
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 298)   overhead slows down opening, but this is hardly
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 299)   noticeable).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 300) - The same get_block()-routine can now be used for
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 301)   both OFS and FFS.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 302) - The super block is now searched in the block that
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 303)   was calculated and in the one following. This
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 304)   should remedy the round-off error introduced by
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 305)   the 1-k blocks that Linux uses.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 306) - Minor changes to adhere to the new VFS interface.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 307) - The number of used blocks is now also calculated
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 308)   if the filesystem is mounted read-only.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 309) - Prefixed some constants with AFFS_ to avoid name
