Subject: exit: proc: don't try to flush /proc/tgid/task/tgid
X-Git-Tag: omap-for-v3.19/fixes-rc1~142^2~11
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c35a7f18a0b237261dad57c9abd3adfa73f315e1;p=pandora-kernel.git

exit: proc: don't try to flush /proc/tgid/task/tgid

proc_flush_task_mnt() always tries to flush task/pid, but this is
pointless if we reap the leader. d_invalidate() is recursive, and
if nothing else the next d_hash_and_lookup(tgid) should fail anyway.
