----------------------------------------------------------------
One of the main highlights this time, is not the patches themselves
but instead the widening contributor base. It is good to see that
interest is increasing in GFS2, and I'd like to thank all the
contributors to this patch set.

In addition to the usual set of bug fixes and clean ups, there are
patches to improve inode creation performance when xattrs are
required and some improvements to the transaction code which is
intended to help improve scalability after further changes in due
course.

Journal extent mapping is also updated to make it more efficient
and again, this is a foundation for future work in this area.

The maximum number of ACLs has been increased to 300 (for a 4k
block size) which means that even with a few additional xattrs
from selinux, everything should fit within a single fs block.

There is also a patch to bring GFS2's own copy of the writepages
code up to the same level as the core VFS. Eventually we may be
able to merge some of this code, since it is fairly similar.

The other major change this time, is bringing consistency to
the printing of messages via fs_<level>, pr_<level> macros.
