The patch titled
proc: fix proc_kill_inodes to kill dentries on all proc superblocks
has been removed from the -mm tree. Its filename was
proc-fix-proc_kill_inodes-to-kill-dentries-on-all-proc-superblocks.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: proc: fix proc_kill_inodes to kill dentries on all proc superblocks
From: Eric W. Biederman <[EMAIL PROTECTED]>
It appears we overlooked support for removing generic proc files
when we added support for multiple proc super blocks. Handle
that now.
