Hi Bo,

Could you please to introduce the motivation of this patch set a little bit more? Thanks.

Hi Li,

Since we want to control COW and compression attribute on a per file or per directory basis,
and find that the generic command "chattr" is the "Mr Right".

Currently only btrfs supports both, of course.

With these patches, we can do the followings:

c: compress
C: nocow

set compress & nocow:

# ./misc/chattr -V +c +C /mnt/btrfs/dir/
chattr 1.41.14 (22-Dec-2010)
Flags of /mnt/btrfs/dir/ set as --------c------C

# ./misc/lsattr -d /mnt/btrfs/dir/
--------c------C /mnt/btrfs/dir/

thanks,
liubo

Thank you for the explaining. Now I understand this patch set is to make chattr of e2fsprogs to support a
(currently-only) btrfs feature.

It seems chattr and lsattr is not an ext[234] only utilities any more...
