I've been working on a set of patches to add a new type file record lock
to the Linux kernel that have less troublesome semantics on close and
that are usable by threaded applications.
I have a blog post here with more details:
http://jtlayton.wordpress.com/2014/01/07/file-private-posix-locks-aka-un-posix-locks/
...and the latest kernel patchset is here:
https://lkml.org/lkml/2014/1/14/554
This patchset represents a set of corresponding updates for glibc. It
just adds the new cmd values to fcntl.h, and a manual update that
discusses how to use the new locks.
I'm currently shooting for a merge in v3.15 kernel so I'm posting this
as an RFC for now.
Comments and suggestions appreciated...
Thanks,

fcntl.h: add new definitions for file-private lock cmd values
