Merge tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2
Pull GFS2 updates from Bob Peterson: "Here is a list of patches we've accumulated for GFS2 for the current upstream merge window. Last window's set was short, but I warned that this one would be bigger, and so it is. We've got 19 patches: - A patch from Abhi Das to propagate the GFS2_DIF_SYSTEM bit so that newly added journals don't get flagged, deleted, and recreated by fsck.gfs2. - Two patches from Andreas Gruenbacher to improve GFS2 performance where extended attributes are involved. - A patch from Andy Price to fix a suspicious rcu dereference error. - Two patches from Ben Marzinski that rework how GFS2's NFS cookies are managed. This fixes readdir problems with nfs-over-gfs2. - A patch from Ben Marzinski that fixes a race in unmounting GFS2. - A set of four patches from me to move the resource group reservations inside the gfs2 inode to improve performance and fix a bug whereby get_write_access improperly prevented some operations like chown. - A patch from me to spinlock-protect the setting of system statfs file data. This was causing small discrepancies between df and du. - A patch from me to reintroduce a timeout while clearing glocks which was accidentally dropped some time ago. - A patch from me to wait for iopen glock dequeues in order to improve deleting of files that were unlinked from a different cluster node. - A patch from me to ensure metadata address spaces get truncated when an inode is evicted. - A patch from me to fix a bug in which a memory leak could occur in some error cases when inodes were trying to be created. - A patch to consistently use iopen glocks to transition from the unlinked state to the deleted state. - A patch to fix a glock reference count error when inode creation fails. - A patch from Junxiao Bi to fix an flock panic. - A patch from Markus Elfring that removes an unnecessary if" * tag 'gfs2-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: gfs2: fix flock panic issue GFS2: Don't do glock put on when inode creation fails GFS2: Always use iopen glock for gl_deletes GFS2: Release iopen glock in gfs2_create_inode error cases GFS2: Truncate address space mapping when deleting an inode GFS2: Wait for iopen glock dequeues gfs2: clear journal live bit in gfs2_log_flush gfs2: change gfs2 readdir cookie gfs2: keep offset when splitting dir leaf blocks GFS2: Reintroduce a timeout in function gfs2_gl_hash_clear GFS2: Update master statfs buffer with sd_statfs_spin locked GFS2: Reduce size of incore inode GFS2: Make rgrp reservations part of the gfs2_inode structure GFS2: Extract quota data from reservations structure (revert 5407e24) gfs2: Extended attribute readahead optimization gfs2: Extended attribute readahead GFS2: Use rht_for_each_entry_rcu in glock_hash_walk GFS2: Delete an unnecessary check before the function call "iput" gfs2: Automatically set GFS2_DIF_SYSTEM flag on system files
