Hello,
ftp://ftp.namesys.com/pub/reiserfs-for-2.4/2.4.15-pre4.pending:
A-expanding-truncate.patch
Patch by Chris Mason <[EMAIL PROTECTED]> to insert indirect items
in a case of expanding truncate. This closes race in a
reiserfs_get_block().
B-sched-yield.patch
This patch fixes typo in fs/reiserfs/journal.c that inadvertently
cleared some flags from current process scheduler policy bitmask,
for example, silently converting real-time processes to normal ones.
C-check_nlink_in_reiserfs_read_inode2.patch
It is possible that knfsd is trying to access inode of a file
that is being removed from the disk by some other thread. As we
update sd on unlink all that is required is to check for nlink
here. This bug was first found by Sizif when debugging
SquidNG/Butterfly, forgotten, and found again after Philippe
Gramoulle <[EMAIL PROTECTED]> reproduced it.
More logical fix would require changes in fs/inode.c:iput() to
remove inode from hash-table _after_ fs cleaned disk stuff up and
in iget() to return NULL if I_FREEING inode is found in
hash-table.
D-bitmap-range-checking.patch
Check that block number are going to free in a bitmap makes sense.
This avoids oops after trying to access bitmap for wild block number.
E-prepare_for_delete_or_cut-cleanup.patch
Patch by Chris Mason <[EMAIL PROTECTED]>.
prepare_for_delete_or_cut() tries to find the unformatted node in
the buffer cache to make sure it isn't in use. Since unformatted
nodes are never in the buffer cache, this check is useless. The
page locking done by mm/vmscan.c:vmtruncate protects us from
truncating away pages that are in use, so it is safe to just remove
the bogus check from our code.
Since the get_hash_table was also the reason for the repeat loop,
this patch removes it as well. Light testing here, I had put an
older version through more tests (before the RFALSE/big endian
stuff), I'll run them again.
This should make file deletes faster, at the very least it cuts down
on CPU overhead for deletes/truncates.
F-cleanup.patch
There is always place for Yet Another Cleanup of Reiserfs Code.
We are going to set up our ftp server to collect logs so that we could
estimate how many times this or that patch was actually downloaded. In
the meantime would everyone actually using test patched please drop a
line to me: [EMAIL PROTECTED]
Nikita.
