[PATCH 0/5][v2] Simplify devpts code

[Sukadev Bhattiprolu]

This patchset tries to address Christoph Hellwig's review comments on the
support for multiple-instances in devpts.  http://lkml.org/lkml/2009/1/3/84
It breaks up the patch into smaller pieces for (hopefully)  easier review.

IIUC, the key observation was that most of do_remount_sb() (MS_RDONLY flag
and shrink_dcache() does not apply to devpts and only the parsing of
options does. Moving the parsing code into devpts enables us to parse
the options just once and vastly simplifies the code.

This patchset does not change any functionality/behavior. But it does
depend on following two related patches.

TODO: (Independent patch set)
