* dirblock.c (ext2fs_write_dir_block): We need to use
|
|
|
|
dirent->rec_len *before* it's byteswapped to find the

|
|

|
|
|
|
to desp ext2 filesystem structures.

|
|
|
|
* bitops.c (set_bit, clear_bit, test_bit): Use modifications
|
|
|
|
supplied by Pete A. Zaitcev so that the C language
|
|
|
|
versions of these functions are more portable. They will
|
|
|
|
now work on both little and big endian systems, and the
|
|
|

of the loop. Factor mask of BLOCK_CHANGED into changed
|
|
|
|
variable out of the loop. (block_iterate_ind, in
|
|
|
|
particular, gets called a lot, so every little
|
|
|
|
optimization helps.)

|
|
|
the S_*, which are normally defined in <sys/stat.h>. This

|
|
|

which may have a different value for S_IFDIR.

|
|
|
|
* closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
|
|
|
|
the EXT2_VALID_FS flag in the backup superblock blocks, so that if
|
|
|
|
someone uses the -b option to specify the use of the backup
|
|
|
|
superblock --- this usually means that the main superblock is
|
|
|

toast. :-)

|
|
|
|
* bitops.h:
|
|
|
|
* openfs.c:
|
|
|
|
* initialize.c: Completely revamped the inode and block bitmap
|
|
|
|
structures, so that they can be better chance of being extensible
|
|
|
|
in a shared library. They are now their own type, instead of
|
|
|
|
being a char *. Also, the function signatures of
|
|
|
|
ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
|
|
|
|
ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
|
|
|
|
ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
|
|
|
|
changed to eliminate the ext2_filsys argument, since it is no
|
|
|
|
longer necessary.

Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
|
|
|
|
|
|
|
|
* unix_io.c (unix_read_blk and unix_write_blk): use the llseek
|
|
|
|
system call if available.
|
|
|
|
|
|
|
|
* llseek.c: new file. This is the stub calling the llseek system
|
|
|
|
call which allows supports for 2GB+ file systems.
|
|
|
|
|
|
|
|
* initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
|
|
|
|
the creator operating system.

Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
|
|
|
|
|
|
|
|
* initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
|
|
|
|
the group descriptor statistics in addition to everything else.
|
|
|
|
This relieves mke2fs of the responsibility of doing it.
|
|
|
|
|
|
|
|
* bitops.c, bitops.h: Add assembly inline functions for the 68000.
|
|
|
|
Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
|
|
|
|
not the generic C function equivalents should be included or not.
|
|
|
|
|
|
|
|
* openfs.c (ext2fs_open): If a superblock is specified, then use
|
|
|
|
the backup group descriptors that go along with this superblock,
|
|
|
|
instead of using the primary group descriptors. This allows
|
|
|
|
e2fsck to recover filesystems where the primary group descriptors
|
|
|
|
have been trashed.
