Hello, This patch adds rollback support for the converter, the converter can roll back a conversion if the image file haven't been modified. In addition, I rearrange some codes in convert.c and add a few comments.

The commit 607d432d referred a static int array defined in ctree.h, and a static inline function (btrfs_super_csum_size) using this array, the obvious problem is every c file using that function would have a local copy of that int array, multiple c files calling would result multiple copies of that array: $ nm fs/btrfs/btrfs.ko | grep btrfs_csum_sizes 0000010c r btrfs_csum_sizes 00000114 r

Commit 699b6faa2ab283219914501d5117f8a93c7e441b allowed btrfs ACLs to be selectable, but put the option in the main fs/Kconfig, and didn''t make it depend on btrfs. This patch moves the option and adds the dependency. Signed-off-by: Jeff Mahoney <jeffm@suse.com> --- fs/Kconfig | 13 ------------- fs/btrfs/Kconfig | 15 +++++++++++++++ 2 files changed, 15

Hi, The following patches add support for ext4 and btrfs to PV-GRUB. These patches are taken nearly verbatim from those provided by Fedora and Gentoo. We''ve been using these patches for the PV-GRUB images available in EC2 for some time now with no problems. Changes from v1: - Makefile has been changed to check the exit code from patch - The btrfs patch has been rebased to apply

This patch adds mixed back ref support for btrfs programs. The mixed back ref is a new disk format. back compatilibity is still not implemented. To try the new disk format, you need fresh formatted btrfs.

After running one too many times into “parent transid verify failed” that prevents a filesystem from being mounted, I found out how to adjust some system blocks so that the kernel could get past that check and mount the filesystem. In one case, I could get all the data I wanted from the filesystem; in another, many checksums failed and I ended up throwing it all away, so no guarrantees.

So both Liu and I made huge messes of find_lock_delalloc_range trying to fix stuff, me first by fixing extent size, then him by fixing something I broke and then me again telling him to fix it a different way. So this is obviously a candidate for some testing. This patch adds a pseudo fs so we can allocate fake inodes for tests that need an inode or pages. Then it addes a bunch of tests to make

Hi gang, I was a little surprised to see that patch go by recently which fixed an endian bug. I went to see how sparse checking looked and it was.. broken. I got it going again in my Fedora environment. Most of the patches are just cleanups, but there *were* three real bugs lurking in all that sparse warning spam. So I maintain that it''s worth our time to keep it going and fix

hello hpa, here my birthday submission :) please pull: git pull git://git.debian.org/users/maks/klibc.git maks Sam fixed a longstanding x86_32 build bug, thus it seems a good time to flush the queue of the piled up patches, the shortlog tells it: Aurelien Jarno (1): [klibc] sh4: syscalls fixes Benjamin Cama (1): [klibc] fstype: btrfs size endianness fix Mike Waychison (2):

We keep hitting bugs in the tree log replay because btrfs_remove_free_space doesn''t account for some corner case. So add a bunch of tests to try and fully test btrfs_remove_free_space since the only time it is called is during tree log replay. These tests all finish successfully, so as we find more of these bugs we need to add to these tests to make sure we don''t regress in

I made an attempt to partly decrease fragment by using a preallocated area of multiple size of a std blocksize for a tree block when it is COWed. The basic idea is that if any a tree block need to be created, we offer, say, 2 or 4 multiples of a std blocksize for it, then use the first block in the continuous blocks. When this block need a cow in the future, a new free block in these continuous

In support of the recently added capability to remount with lzo compression, provide a helper function to check the compression INCOMPAT flags when remounting with lzo compression, and set the flags if necessary. Also, implement the new helper function when defragmenting with explicit lzo compression and when setting the default subvolume. Signed-off-by: Mitch Harder

Older kernels would generally be able to still mount the filesystem with the default subvolume set, but it would result in a different volume being mounted, which could be an even more unpleasant suprise for users. So if you set your default subvolume, you can''t go back to older kernels. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com> --- fs/btrfs/ctree.h | 4 +++-
