Btrfs: Show discard option in /proc/mounts
Christoph's patch e244a0aeb6a599c19a7c802cda6e2d67c847b154 doesn't display the discard option in /proc/mounts, leading to some confusion for me. Here's the missing bit. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
