Subject: [PATCH 35/35] staging: lustre: idl: clean up file attribute flags

From: Andreas Dilger <andreas.dilger@...el.com>

Remove unused file attribute flag LUSTRE_BFLAG_UNCOMMITTED_WRITES
that was used internally on the client at one point.

Add flags from the kernel which may be useful in the near future.
