Cover letter [PATCH 0/2] xfs buf I/O error race test

Hi all,

Here's a complete test for the XFS buf I/O error race problem reported by Alex. An incomplete rfc of this test was previously posted here:

http://oss.sgi.com/archives/xfs/2014-08/msg00261.html

This version utilizes the recently posted log recovery delay mechanism. As such, this test only runs on kernels compiled with XFS debug support. The first patch updates the generic require sysfs helper to support global (i.e., non-device specific) sysfs attributes.
