SubjectRe: [PATCH 14/16] isdn: divert, hysdn: fix interruptible_sleep_on race
From: Arnd Bergmann <>
Date: Wed, 26 Feb 2014 12:01:54 +0100

> These two drivers use identical code for their procfs status
> file handling, which contains a small race against status
> data becoming available while reading the file.
> This uses wait_event_interruptible instead to fix this
> particular race and eventually get rid of all sleep_on
> instances. There seems to be another race involving
> multiple concurrent readers of the same procfs file, which
> I don't try to fix here.
