[PATCH v7 00/17] locks: fixes for 3.15 and file-private lock support

[Jeff Layton <jlayton@redhat.com>]

This is a re-posting of patches that I have queued for 3.15. There's
really nothing new in this pile vs. the last several sets that I've
posted. This is mainly just a re-posting of them all as one complete
set. The only real difference is a fix for one of the mandatory locking
patches when CONFIG_FILE_LOCKING is disabled (many thanks to AKPM for
pointing that out).

Most of this pile has been sitting in linux-next since 3.14-rc1, and
I've heard zero complaints aside from a minor merge conflict with one of
Heiko Carstens's patches. A few patches were added later and haven't
been soaking in linux-next for as long, but they've been there for a
little while now.

Al would you be willing to take these into your tree and merge them up
to Linus for 3.15 (assuming no one objects, of cours)? It may be easier
to cherry pick them from my linux-next branch:

Thanks! Comments and suggestions welcome...
