Subject: vfs: new superblock methods to override /proc/*/mount{s,info}
X-Git-Tag: v2.6.39-rc1~460^2~3

vfs: new superblock methods to override /proc/*/mount{s,info}

a) ->show_devname(m, mnt) - what to put into devname columns in mounts,
mountinfo and mountstats
b) ->show_path(m, mnt) - what to put into relative path column in mountinfo

Leaving those NULL gives old behaviour.  NFS switched to using those.
