This e-mail describes the OCFS2 patches which I intend to push
upstream to Linus for 2.6.20.
* Various ocfs2 cleanups, including a patchset by me intended to clean up
some of the internal ocfs2 journal api. Mostly this revolves around
removing the ocfs2_journal_handle wrapper around handle_t. The immediate
benefits are better readability and a slightly smaller memory footprint
for open journal transactions.
* Configfs gets some small cleanups and some mutex annotations.
* Atime updates - thanks to Tiger Yang <[email protected]>, ocfs2 now
writes to the inode atime field. This doesn't require any disk changes,
and is completely backwards compatible with older ocfs2 versions. An
inodes Atime is only updated if it hasn't changed within a certain
quantum. The user can define their own value at mount time, with 0
indicating that atime should always be updated. This is very similar to
the scheme implemented by gfs2. In the future, I'd like to see a "relative
atime" mode, which functions in the manner described by Valerie Henson at:
http://lkml.org/lkml/2006/8/25/380
* sys_splice - ocfs2 now has splice read and write support. Thanks again to
Tiger for the bulk of this functionality. Mostly we make use of the
generic_splice_read() and generic_file_splice_write_nolock() functions
provided already in fs/splice.c.
- There is one patch in the ocfs2 splice() series external to fs/ocfs2 - a
simple export of should_remove_suid(). This is done for code reuse
purposes. That particular patch can be seen at:
http://ftp.kernel.org/pub/linux/kernel/people/mfasheh/ocfs2/ocfs2_git_patches/ocfs2-upstream-linus-20061201/0025-Export-should_remove_suid.txt
I'll also attach it to this mail for review purposes.
* Last in the list of notable patches is a somewhat involved fix by Kurt
Hackel <[email protected]> within the ocfs2 dlm. We had temporarily
disable automatic migration of certain lock types because it was causing
us problems during stress testing. This patch fixes those problems and
re-enables migration. Overall this should reduce memory usage of the ocfs2
dlm.
The patches can be found in
git://git.kernel.org/pub/scm/linux/kernel/git/mfasheh/ocfs2.git upstream-linus
Additionally, broken out patches are available at:

Thanks,

This helps us avoid replicating the same logic within file system drivers.
