This patch has been added to the 3.12 stable tree. If you have any
objections, please let us know.
===============
commit a6b1533e9a57d76cd3d9b7649d29ac604b1874b8 upstream.
Replace wait_event_killable with wait_event_interruptible
so that a program waiting for a posix lock can be
interrupted by a signal. With the killable version,
a program was not interruptible by a signal if it
had a signal handler set for it, overriding the default
action of terminating the process.
