Hello!
Attached patch contains these 24 patches (all in one as you requested):
01-corrupt_items_checks.diff
Certain disk corruptions may end-up making item-type to be garbage. This
patch makes reiserfs not to crash when dealing with such items.
02-ioerrors-checks-2.diff
Correctly check return value of reiserfs_find_entry for io errors.
03-key_output_fix.diff
Correctly output cpu keys as %K
04-mkdir_nospace_nowarning.diff
Do not print warnings if cannot create a dir due to no free space.
05-non4kpages_size_fix.diff
Fix a case where filesizes in blocks could be incorrectly
determined if pagesize != blocksize
06-return_braindamage_removal.diff
Removal of some dead code that never can be executed.
07-rm_truncate_nospace_nowarn.diff
Do not print a warning if we cannot insert rm/truncate record into the
tree due to no space condition
08-savelink_nospace_nowarning.diff
Do not print a warning if we cannot inser a savelink item into the tree due
to no space condition.
09-tailconv_nospace_nowarn.diff
Do not print a warning if we cannot conwert file tail into ordinar page
due to no space condition.
10-unfinished_rebuildtree_message.diff
Print a hint for a user if we encounter a filesystem that was not correctly
processed by reiserfsck --rebuild-tree
11-reiserfs-bitmap-journal-read-ahead.diff
Read-ahead of journal bitmaps, this should speed-up mount times in case of
journal replay. Especially on rebuilding RAID arrays.
12-v3.6_uuid_support-1.diff
Add some support for UUID and LABELs on v3.6 filesystems.
13-pap14030-not-crash-2.diff
Fix a problem where subsequent get_block() failures may lead to incorrect
data in page case marced as uptodate.
14-remount-options.diff
Add support for more remount options.
15-more-procfs.diff
Add more vatiables to reiserfs procfs monitoring interface
16-blocksize_lessthan_pagesize_fix.diff
Fixes a bug in case we have pagesize > blocksize and active
buffers flushing.
17-kmalloc_cleanup.diff
Convert all kmalloc's into the reiserfs_kmallocs. Make reiserfs_kmalloc to
be of no extra overhead in case CONFIG_REISERFS_CHECK was not selected.
18-hash_autodetect_fix.diff
Fix hash autodetecting.
19-inode-attrs.diff
Add support for ext2-style inode attributes. Note, you must use -o attrs
flag, also you must have previous attribute contents cleaned and special
flag set in the superblock.
20-unlink_print_nogarbage.diff
Do not print garbage priority level on savelinks replay.
21-docupdate.diff
Update current reiserfsprogs information, fix "unused variable" warning.
22-atime_fix.diff
Correctly update atime on file access.
23-truncate-fix.diff
Add missed journal_begin call for a case where direct2indirect failed, but
block for this conversion was already allocated and needs to be freed.
24-o_direct.diff
Add O_DIRECT support.
Bye,
Oleg
