hello, Chris In the next several months, I will have a lot of spare time. I will be happy if you assign some work to me. I have learn linux kernel for years but only fix a few small bugs in IP stack. In the past few months, I read some EXT4/VFS codes. I began reading source of btrfs ten days ago and have read it twice now. Regards YZ

There are three patches at http://www.zip.com.au/~akpm/linux/patches/2.4/2.4.20/ sync_fs.patch: Fix the ext3 data=journal data-loss-on-unmount bug sync_fs-fix.patch: Fix sync_fs.patch to not deadlock the fs when running `mount -o remount' against a heavily loaded filesystem. ext3-use-after-free.patch Fix a use-after-free bug which can cause memory corruption if the filesystem runs

A bunch of fixes (memory leaks, NULL pointer dereferences and devices hanging in busy state) to sanitize error handling during mount sequence. This is on top of for-linus + slyfox''s double-free fix. Thanks, Ilya Ilya Dryomov (5): Btrfs: fix memory leak in btrfs_parse_early_options() Btrfs: fix subvol_name leak on error in btrfs_mount() Btrfs: avoid null dereference and leaks

I'm running a bit late with the e-mail this time around, but I think that's ok since there really isn't any major new features here - the bulk of the Ocfs2 update is bug fixes, or cleanups. The same goes for configfs. The only two things that could be described as features would be: - Sunil has updated Ocfs2 to provide even more live cluster locking information via debugfs. - Joel

Hi, This is the second batch of Ocfs2 patches intended for the merge window. The 1st batch were sent out previously: http://lkml.org/lkml/2008/12/19/280 The bulk of this set is comprised of Jan Kara's patches to add quota support to Ocfs2. Many of the quota patches are to generic code, which I carried to make merging of the Ocfs2 support easier. All of the non-ocfs2 patches should have
