Subject: Updated ext4 patchset


There's a new ext4 patchset available, here:

As a git tree:

git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git 2.6.26-rc2-ext4-1
http://git.kernel.org/?p=linux/kernel/git/tytso/ext4.git;a=shortlog;h=2.6.26-rc2-ext4-1

As a patchset:

ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/ext4-patches/2.6.26-rc2-ext4-1

The bug fixes patches marked as with an "+" below probably be pushed to
Linus fairly shortly.


The double "There are a few cases direct IO could race with kjournal
flushing" that are credited to me are from two patches,
jbd-dio-kjournal-race-EIO.patch, and jbd2-dio-kjournal-race-EIO.patch,
where I didn't notice the patches weren't correctly formatted until
after I had cut the patch series.

Unfortunately I missed this until after I made the patch series, but
I'll fix it before those patches are pushed to Linus --- or better yet,
if someone else wants to fix it, and be careful to make sure new patches
added to the patch queue are correctly formatted, even better.  :-)

There was similar problem with Julia Lawall's patch which was missing a
one-line description that has already been fixed in the patch queue.


Just as a reminder, the correct format is a single one-line description
(under 70 characters long, please) followed by a blank line, followed by
a "From: John. Q. Author <author@...the.patch.com>", followed by another
blank line, followed by the patch description.  (For the patch
description, please check out other git commits to get an idea of the
appropriate writing style and detail that is needed.)

Also, note that Andrew gets cranky when we push fs/jbd or fs/ext3
patches through the ext4 tree.  So we really should get that into
Andrew's -mm tree, and then dropped from ours.

Finally, while I'm carping about consistency and style of the git
headers, how about using all lower case for "ext4" or "jbd2", followed
by a colon, followed by a single space, hmm?  It's a minor point, but it
looks nicer in gitk if they are all consistent, instead of some patches
using "jbd2: ", some with "Jbd2: ", and some with "JBD2:  ".

Thanks,
