Subject: [mmots][next-20130725] "ipc,shm: dont leave do_shmat with rcu lock
 held" needs a refresh

Hi,

I have tested the IPC patches in mmots which are not in current mmotm
against next-20130725.

Unfortunately, the 1st one needs a refresh (see attached patch).

As a bonbon, I have tested with LTP (see attached results file). It looks good.

Regards,
