Subject[PATCH -next 0/5] ipc: EIDRM/EINVAL returns & misc updates

Patches 1,2: Are a resend, I've incorporated them to the set,
based on Manfred's comments.

Patch 3: is a trivial function rename.

Patches 4,5: are attempts to order how Linux ipc deals with EIDRM
and EINVAL return error codes. By looking at corresponding manpages
two possible inverted return codes are returned, these patches
make the manpages accurate now -- but I may have missed something,
and we are changing semantics. afaik EIDRM is specific to Linux
(other OSes only rely on EINVAL), which is already messy, so lets
try to make this consistent at least.

Passes all ipc related ltp tests.


Davidlohr Bueso (5):
ipc,shm: move BUG_ON check into shm_lock
ipc,msg: provide barrier pairings for lockless receive
ipc: rename ipc_obtain_object
ipc,sysv: make return -EIDRM when racing with RMID consistent
ipc,sysv: return -EINVAL upon incorrect id/seqnum

ipc/msg.c | 50 +++++++++++++++++++++++++++++++++++++++-----------
ipc/sem.c | 4 ++--
ipc/shm.c | 13 ++++++++-----
ipc/util.c | 23 +++++++++++++----------
ipc/util.h | 2 +-
