#     Merge branch 'userns-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull namespace updates from Eric Biederman:
#      "There was a lot of work this cycle fixing bugs that were discovered
#       after the merge window and getting everything ready where we can
#       reasonably support fully unprivileged fuse. The bug fixes you already
#       have and much of the unprivileged fuse work is coming in via other
#       trees.
#     
#       Still left for fully unprivileged fuse is figuring out how to cleanly
#       handle .set_acl and .get_acl in the legacy case, and properly handling
#       of evm xattrs on unprivileged mounts.
#     
#       Included in the tree is a cleanup from Alexely that replaced a linked
#       list with a statically allocated fix sized array for the pid caches,
#       which simplifies and speeds things up.
#     
#       Then there is are some cleanups and fixes for the ipc namespace. The
#       motivation was that in reviewing other code it was discovered that
#       access ipc objects from different pid namespaces recorded pids in such
#       a way that when asked the wrong pids were returned. In the worst case
#       there has been a measured 30% performance impact for sysvipc
#       semaphores. Other test cases showed no measurable performance impact.
#       Manfred Spraul and Davidlohr Bueso who tend to work on sysvipc
#       performance both gave the nod that this is good enough.
#     
#       Casey Schaufler and James Morris have given their approval to the LSM
#       side of the changes.
#     
#       I simplified the types and the code dealing with sysvipc to pass just
#       kern_ipc_perm for all three types of ipc. Which reduced the header
#       dependencies throughout the kernel and simplified the lsm code.
#     
#       Which let me work on the pid fixes without having to worry about
#       trivial changes causing complete kernel recompiles"
