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

[Brian Foster]

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.

Brian

v1:
- Use the log recovery delay mechanism to coordinate I/O failures with
log recovery.
