[PATCH v3 0/6] Btrfs: show subvolume name and ID in /proc/mounts

[Omar Sandoval <osandov@osandov.com>]

Now that we've reached an agreement, I've rebased this series on top of
v4.1-rc3 (there were some minor conflicts with the ->d_inode to
d_inode() conversion merged in v4.1-rc1, no other code changes).

This change makes things just a little bit friendlier for users and also
cleans up the mount path. David mentioned that he's also using this
patchset as a base for per-subvolume mount flag support. He's reviewed
all of the patches in this series. Please consider for 4.2!
