Subject: [PATCH] Btrfs-progs: add incompat flag for space cache inode
Date: Wed, 27 Oct 2010 14:29:39 -0400	[thread overview]
Message-ID: <1288204179-1764-1-git-send-email-josef@redhat.com> (raw)

This patch adds the incompat flag for the space cache inode stuff.  Eventually
we'll want to turn this feature on at mkfs time, but for now lets let it settle
a bit first.  Thanks,

Signed-off-by: Josef Bacik <josef@redhat.com>
