Subject: [PATCH] proc: fix missing reference of mm
Date: Thu, 21 Jan 2016 10:25:28 +0530 [thread overview]
Message-ID: <1453352128-29863-1-git-send-email-sudipm.mukherjee@gmail.com> (raw)
The defconfig build of blackfin was failing with the error:
fs/proc/task_nommu.c: In function 'is_stack':
fs/proc/task_nommu.c:132:28: error: 'mm' undeclared (first use in this function)
While reverting /proc/<pid>/maps [stack:TID] annotation a reference to
mm was missed.
Fixes: e87d4fd02f40 ("proc: revert /proc/<pid>/maps [stack:TID] annotation")
