Subject: [PATCH 3.12 038/181] xfs: don't emit corruption noise on fs probes

From: Eric Sandeen <sandeen@...deen.net>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 31625f28ad7be67701dc4cefcf52087addd88af4 upstream.

If we get EWRONGFS due to probing of non-xfs filesystems,
there's no need to issue the scary corruption error and backtrace.
