Subject: proc: Point /proc/mounts at /proc/thread-self/mounts instead of /proc/self/mounts
X-Git-Tag: firefly_0821_release~176^2~3424^2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=344470cac42e;p=firefly-linux-kernel-4.4.55.git

proc: Point /proc/mounts at /proc/thread-self/mounts instead of /proc/self/mounts

In oddball cases where the thread has a different mount namespace than
the thread group leader or more likely in cases where the thread
remains and the thread group leader has exited this ensures that
/proc/mounts continues to work.

This should not cause any problems but if it does this patch can just
be reverted.
