Merge tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw
Pull GFS2 updates from Steven Whitehouse: "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" * tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-nmw: (29 commits) GFS2: Fix address space from page function GFS2: Fix uninitialized VFS inode in gfs2_create_inode GFS2: Fix return value in slot_get() GFS2: inline function gfs2_set_mode GFS2: Remove extraneous function gfs2_security_init GFS2: Increase the max number of ACLs GFS2: Re-add a call to log_flush_wait when flushing the journal GFS2: Ensure workqueue is scheduled after noexp request GFS2: check NULL return value in gfs2_ok_to_move GFS2: Convert gfs2_lm_withdraw to use fs_err GFS2: Use fs_<level> more often GFS2: Use pr_<level> more consistently GFS2: Move recovery variables to journal structure in memory GFS2: global conversion to pr_foo() GFS2: return -E2BIG if hit the maximum limits of ACLs GFS2: Clean up journal extent mapping GFS2: replace kmalloc - __vmalloc / memset 0 GFS2: Remove extra "if" in gfs2_log_flush() fs: NULL dereference in posix_acl_to_xattr() GFS2: Move log buffer accounting to transaction ...
