The patch titled
__mutex_lock_common: use signal_pending_state()
has been removed from the -mm tree. Its filename was
__mutex_lock_common-use-signal_pending_state.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: __mutex_lock_common: use signal_pending_state()
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Change __mutex_lock_common() to use signal_pending_state() for the sake of
the code re-use.
This adds 7 bytes to kernel/mutex.o, but afaics only because gcc isn't smart
enough.
(btw, uninlining of __mutex_lock_common() shrinks .text from 2722 to 1542,
perhaps it is worth doing).
