similar to: [PATCH] btrfs-progs: mkfs: add -O option to specify fs features

This adds the flag to ctree.h, adds the feature option to mkfs to turn it on and fixes fsck so it doesn''t complain about missing hole extents in files when this flag is set.

The following case will make the incompat/compat flag of the super block be recovered. Task1 |Task2 flags = btrfs_super_incompat_flags(); | |flags = btrfs_super_incompat_flags(); flags |= new_flag1; | |flags |= new_flag2; btrfs_set_super_incompat_flags(flags); | |btrfs_set_super_incompat_flags(flags); the new_flag1 is recovered. In order to avoid this problem, we

This fixes up the progs to properly deal with skinny metadata. This adds the -x option to mkfs and btrfstune for enabling the skinny metadata option. This also makes changes to fsck so it can properly deal with the skinny metadata entries.

Hello, This is the userspace part of restriper, rebased onto the new progs infrastructure. Restriper commands are located under ''balance'' prefix, which is now the top level command group. However to not confuse existing users ''balance'' prefix is also available under ''filesystem'': btrfs [filesystem] balance start btrfs [filesystem] balance

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 +++-

Btrfs has always had these filler extent data items for holes in inodes. This has made somethings very easy, like logging hole punches and sending hole punches. However for large holey files these extent data items are pure overhead. So add an incompatible feature to no longer add hole extents to reduce the amount of metadata used by these sort of files. This has a few changes for logging and

Hi, so here it is, LZ4 compression method inside btrfs. The patchset is based on top of current Chris'' for-linus + Andi''s snappy implementation + the fixes from Li Zefan. Passes xfstests and stresstests. I haven''t measured performance on wide range of hardware or workloads, rather wanted to publish the patches before I get distracted again. I''d like to ask

WARNING: This is not compatible with the previous lz4 patchset. If you''re using experimental compression that isn''t in mainline kernels, be prepared to backup and restore or decompress before upgrading, and have backups in case it eats data (which appears not to be a problem any more, but has been during development). These patches add lz4 and lz4hc compression

Hello, This patch series adds an initial implementation of restriper (it''s a clever name for relocation framework that allows to do selective profile changing and selective balancing with some goodies like pausing/resuming and reporting progress to the user. Profile changing is global (per-FS) so far, per-subvolume profiles require some discussion and can be implemented in future.
