Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git for_linus
This is the major set of updates meant for 2.6.24 from the ext4 team;
these patches have been baking in -mm for a while. The two major
features included here is the multi-block allocator that has been in use
by Clusterfs for their luster filesystem, as well as the journal
checksumming features. There were also a huge number of clean ups and
various bug fixes.
Regards,
- Ted

That's because you are doing a diff stat of changes that haven't been
checked in yet. I was doing a "git log -p origin.. | diffstat -p1",
and in that incantation you definitely do need the -p1 to diffstat.

How about git diff --stat origin.. ?

You should *always* use "-p1" to diffstat, because if you don't, diffstat
just makes up the paths totally (the same way you should always use "-p1"
to GNU 'patch').
The fact is, diffstat just guesses, based on the prefix. But those guesses
will be totally bogus at times, especially if you have newly created files
(I _think_ that is because one of the pathnames in the diff is /dev/null,
and that will apparently throw off the guesses).
So if you don't use an explicit "-p1", diffstat will guess the -p level
from the longest common path prefix, _but_ get that wrong for some paths
anyway, so sometimes you'll see the "a/" prefix etc.
Of course, rather than using diffstat at all, just do something like
git diff --stat origin..
instead.

Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git for_linus
These are mostly bug fixes that we've found since the last pull request.
The one non-bugfix change is that I've added a sanity check to assure
that production ext3 filesystems don't get mounted with ext4dev
accidentally. The need for this was discovered when Eric Sandeen
started putting ext4 into Fedora's Rawhide release for initial testing.
Thanks,
- Ted

Hi Linus,
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git for_linus
It has a number random cleanups and bug fixes, and two new features.
The first is uninitialized block groups, which allows fast mke2fs
operations plus as well as speeding up e2fsck by allowing it to skip
parts of the inode tables that haven't been used yet. A checksum has
been added to block group descriptors so we can tell detect corruption
in that data structure, since we are depending on it being accurate so
we know what portion of the inode table is really in use.
The second feature is flexible block groups, which allows inode tables
and block/inode bitmaps to be grouped together outside of the block
group that they administer, to allow contiguous regions of data blocks
to span multiple block groups, which helps for large files significantly
bigger than the size of a block group (i.e., 32 gigabytes on a 4k block
filesystem).
All of these patches have been baking in -mm for a while.
Regards,
- Ted

nice feature, is there any work on a tool to go through a well-used
filesystem and mark unused block groups as uninitialized? (I would guess
that such a tool may want to move files to make this so)

Yes, just set the feature flag via tune2fs and then run e2fsck on it.
The second e2fsck shown below is just a demonstration of the speedup.
# tune2fs -O uninit_groups /dev/foo
tune2fs 1.39.cfs9 (7-Apr-2007)
Please run e2fsck on the filesystem.
# time e2fsck -fy /dev/foo
e2fsck 1.39.cfs9 (7-Apr-2007)
Group descriptor 0 checksum is invalid. Fix? yes
{repeats for all groups}
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information

user 0m4.930s

blocks
real 0m2.412s
user 0m0.604s
sys 0m0.077s
The caveats are:
(a) this is a read-only feature, so you can't mount such a filesystem r/w
on an older kernel. You can disable it with "tune2fs -O ^uninit_groups"
and run a full e2fsck on it again.
(b) I don't think there is an official e2fsprogs release with support for this
feature yet (it's in the pipe, however).
(c) The actual speedup depends on how full the filesystem is, but since ext*
usually has way too many inodes, it is generally pretty good.
Cheers, Andreas

OK, I've rebased and fixed up the patches with your latest git tree.
Could you please pull from:

There shouldn't have been conflicts here - if there were I wouldn't have
sent those patches. Unless there were things in the ext4 pull which
weren't present in the ext4 quilt tree which I included in 2.6.23-mm1?

Well, you merge your patch-series by patching.
You should have noticed by now that GNU patch in particular will happily
apply a patch whether it conflicts or not. So it's entirely possible that
it didn't conflict for you, but applied cleanly and sanely.

hrm, could be. It would be strange for that to happen quietly with fuzz=1
and to still produce a compileable result.
But there weren't any patches in this git-merge which weren't in 2.6.23-mm1
so maybe something like that happened. Or maybe that fact that this pull
only contained _some_ of the ext4 patches which were in -mm somehow affected
things.
Oh well, I should have sent the ext4 changes via Ted anyway.

Hi Linus,
Please pull from:

It contains the following feature enhancements, including support for
the new fallocate() system call. These have been in -mm for a while,
consensus reached for the fallocate() interface between other filesystem
and architecture maintainers. Patches to wire up the other arches and
XFS should be showing up shortly after this gets merged into mainline.
