Hi all,

Here's v2 of sysfs support for XFS. The previous version is available
here:

http://oss.sgi.com/archives/xfs/2014-06/msg00141.html

This version is rebased onto the latest for-next and further cleans up
the code to use some abstractions for sysfs object maintenance and
associated helpers. As noted in the v1 thread, I think the current doc
patch already indicates that the sysfs attrs are not considered stable.
Unless there is further feedback on that front, I'll leave that patch as
is.

v2:
- Rebased to latest for-next (error negation, libxfs).
- Introduce xfs_kobj container for kobject and completion.
- Genericize kobject release function.
- Move snprintf() outside of iclog lock in log_head_lsn_show(). Clean up
xlog handlers.
v1:
- Move sysfs infrastructure code to new source file, add helpers for
object initialization, etc.
- Created an xfs_mount->xlog object heirarchy for attributes associated
with the log.
- Renamed the reserve/write grant head attributes to
'[reserve,write]_grant_head.'
- Use the 'cycle:block' or 'cycle:bytes' decimal format for attributes
(rather than export encoded values).
- Included generic mountfs fix and doc.
