This series addresses the problem of showing mount options in
/proc/mounts.

.show_options superblock operation. Several others have implemented
this callback, but have not kept it
From: Miklos Szeredi <[EMAIL PROTECTED]>
Add a .show_options super operation to devpts.
Also add minor fix: when parsing the "mode" option, mask with
S_IALLUGO instead of ~S_IFMT, which could leave unsed bits in the
mask.
