The following series implement a way to generate the help messages and the btrfs man page from the sources comments for the "btrfs" commanda . The syntax and the detailed help of every subcommand are stored in the comments before the function which implements the subcommand. The fact that the help messages and the man page are generated from the same source should help to avoid

Hi All, the following patches implement the recursively snapshotting and deleting of a subvolume. To snapshot recursively you must pass the -R switch: # btrfs subvolume create sub1 Create subvolume ''./sub1'' # btrfs subvolume create sub1/sub2 Create subvolume ''sub1/sub2'' # btrfs subvolume snapshot -R sub1 sub1-snap Create a snapshot of

From: Anand Jain <anand.jain@oracle.com> (This patch is for the review/test not yet for the integration). Here is an implementation of the feature to add label to the subvolume and snapshots. Which would help sysadmin to better manager the subvol and snapshots. This can be done in two ways, one - using attr which is user land only changes but drawback is able to change the label

- Add incompat flag, otherwise btrfs-progs will report error when operating on btrfs filesystems mounted with lzo option. - Allow to turn on lzo compression for defrag operation: # btrfs filesystem defragment -c[zlib, lzo] <file> Note: "-c zlib" will fail, because that''s how getopt() works for optional arguments.

Hi Chris, this serie of patches updated the command "btrfs filesystem df". I update this command because it is not so easy to get the information about the disk usage from the command "fi df" and "fi show". This patch was the result of some discussions on the btrfs mailing list. Many thanks to all the contributors. From the man page (see 2nd patch): [...] The
