Subject: [PATCH 00/12] Assorted lustre fixes and improvements

Hi,
 I've been looking through lustre, finding things, and fixing some of
 them.
 There are three distinct subsets of patches here.
 - 1 patch to fix a few typos in comments
 - 2 patches to fix dcache issues, particularly around
    DCACHE_DISCONNECTED
 - 9 patches to clean up code in ldlm_flock().  These started
   as some simple list_entry tidy-ups, and just grew....

 The most interesting from a review perspective is
      staging: lustre: llite: fix various issues with ll_splice_alias.
 there are real locking issues in there, but its hard to be 100%
 sure I've fixed them all and not introduced new issues.
 It would be *really* nice if we could get rid of the concept of
 "invalid" dentries, but I don't yet understand it well enough to
 propose and alternative.

Thanks,
NeilBrown
