Subject: - jbd2-only-create-debugfs-and-stats-entries-if-cache-initialisation-is-successful.patch removed from -mm tree


The patch titled
     jbd2: only create debugfs and stats entries if cache initialisation is successful
has been removed from the -mm tree.  Its filename was
     jbd2-only-create-debugfs-and-stats-entries-if-cache-initialisation-is-successful.patch

This patch was dropped because it was merged into mainline or a subsystem tree

The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: jbd2: only create debugfs and stats entries if cache initialisation is successful
From: "Duane Griffin" <duaneg@...da.com>

jbd2 debugfs and stats entries should only be created if cache initialisation
is successful.  At the moment they are being created unconditionally which
will leave them dangling if cache (and hence module) initialisation fails.
