From a6b1533e9a57d76cd3d9b7649d29ac604b1874b8 Mon Sep 17 00:00:00 2001 From: Eric Ren Date: Wed, 14 Oct 2015 23:28:26 +0800 Subject: [PATCH] dlm: make posix locks interruptible 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.
