Alexander Zarochentsev a44c94a7b8 [PATCH] reiserfs: handle trans_id overflow
Reiserfs does not handle transaction ID overflow correctly.  Transaction ID
== 0 causes reiserfs to crash.  The patch fixes all places where the
transaction ID is incremented.

Chris Mason e0e851cf30 [PATCH] reiserfs: reiserfs hang and performance fix for data=journal mode
In data=journal mode, reiserfs writepage needs to make sure not to trigger
transactions while being run under PF_MEMALLOC.  This patch makes sure to
redirty the page instead of forcing a transaction start in this case.

Also, calling filemap_fdata* in order to trigger io on the block device can
cause lock inversions on the page lock.  Instead, do simple batching from
flush_commit_list.

Chris Mason d62b1b87a7 [PATCH] resierfs: fix reiserfs_invalidatepage race against data=ordered
After a transaction has closed but before it has finished commit, there is
a window where data=ordered mode requires invalidatepage to pin pages
instead of freeing them.  This patch fixes a race between the
invalidatepage checks and data=ordered writeback, and it also adds a check
to the reiserfs write_ordered_buffers routines to write any anonymous
buffers that were dirtied after its first writeback loop.

That bug works like this:

proc1: transaction closes and a new one starts
proc1: write_ordered_buffers starts processing data=ordered list
proc1: buffer A is cleaned and written
proc2: buffer A is dirtied by another process
proc2: File is truncated to zero, page A goes through invalidatepage
proc2: reiserfs_invalidatepage sees dirty buffer A with reiserfs
       journal head, pins it
proc1: write_ordered_buffers frees the journal head on buffer A

At this point, buffer A stays dirty forever

Jan Kara ef43bc4fc3 [PATCH] reiserfs: fix assertion failure in reiserfs+journaled quotas
Sometimes we call do_journal_end() with t_refcount == 0.  If quota is
turned on and we happen to have some inode with preallocation bad things
happen as we try to use the current handle for quota operations.  Checks
for t_refcount in journal_begin() fail and we Oops.  We raise t_refcount to
make those checks happy.  We should not cause any bad as all the needed
quota blocks should be already attached to the transaction (they were
attached to the transaction when we allocated those preallocation blocks).

Jeff Mahoney 5d5e815618 [PATCH] reiserfs: skip commit on io error
This should have been part of the original io error patch, but got
dropped somewhere along the way.

It's extremely important when handling the i/o error in the journal to
not commit the transaction with corrupt data.  This patch adds that code
back in.

Jeff Mahoney 576f6d7956 [PATCH] reiserfs: handle cnode allocation failure gracefully
If an external device is used for a journal, by default it will use the
entire device.  The reiserfs journal code allocates structures per journal
block when it mounts the file system.  If the journal device is too large,
and memory cannot be allocated for the structures, it will continue and
ultimately panic when it can't pull one off the free list.

This patch handles the allocation failure gracefully and prints an error
message at mount time.

Changes: Updated error message to be more descriptive to the user.

Discussed and approved on ReiserFS Mailing List, Nov 28.

Jesper Juhl 77933d7276 [PATCH] clean up inline static vs static inline
`gcc -W' likes to complain if the static keyword is not at the beginning of
the declaration.  This patch fixes all remaining occurrences of "inline
static" up with "static inline" in the entire kernel tree (140 occurrences in
47 files).

While making this change I came across a few lines with trailing whitespace
that I also fixed up, I have also added or removed a blank line or two here
and there, but there are no functional changes in the patch.

Linus Torvalds bd4c625c06 reiserfs: run scripts/Lindent on reiserfs code
This was a pure indentation change, using:

	scripts/Lindent fs/reiserfs/*.c include/linux/reiserfs_*.h

to make reiserfs match the regular Linux indentation style.  As Jeff
Mahoney <jeffm@suse.com> writes:

 The ReiserFS code is a mix of a number of different coding styles, sometimes
 different even from line-to-line. Since the code has been relatively stable
 for quite some time and there are few outstanding patches to be applied, it
 is time to reformat the code to conform to the Linux style standard outlined
 in Documentation/CodingStyle.

 This patch contains the result of running scripts/Lindent against
 fs/reiserfs/*.c and include/linux/reiserfs_*.h. There are places where the
 code can be made to look better, but I'd rather keep those patches separate
 so that there isn't a subtle by-hand hand accident in the middle of a huge
 patch. To be clear: This patch is reformatting *only*.

 A number of patches may follow that continue to make the code more consistent
 with the Linux coding style.

 Hans wasn't particularly enthusiastic about these patches, but said he
 wouldn't really oppose them either.

Jens Axboe 22e2c507c3 [PATCH] Update cfq io scheduler to time sliced design
This updates the CFQ io scheduler to the new time sliced design (cfq
v3).  It provides full process fairness, while giving excellent
aggregate system throughput even for many competing processes.  It
supports io priorities, either inherited from the cpu nice value or set
directly with the ioprio_get/set syscalls.  The latter closely mimic
set/getpriority.

This import is based on my latest from -mm.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
