Pull GFS2 updates from Bob Peterson: "Here are the patches we've accumulated for GFS2 for the current upstream merge window. We have a good mixture this time. Here are some of the features: - Fix a problem with RO mounts writing to the journal. - Further improvements to quotas on GFS2. - Added support for rename2 and RENAME_EXCHANGE on GFS2. - Increase performance by making glock lru_list less of a bottleneck. - Increase performance by avoiding unnecessary buffer_head releases. - Increase performance by using average glock round trip time from all CPUs. - Fixes for some compiler warnings and minor white space issues. - Other misc bug fixes" * tag 'gfs2-merge-window' of git://git.kernel.org:/pub/scm/linux/kernel/git/gfs2/linux-gfs2: GFS2: Don't brelse rgrp buffer_heads every allocation GFS2: Don't add all glocks to the lru gfs2: Don't support fallocate on jdata files gfs2: s64 cast for negative quota value gfs2: limit quota log messages gfs2: fix quota updates on block boundaries gfs2: fix shadow warning in gfs2_rbm_find() gfs2: kerneldoc warning fixes gfs2: convert simple_str to kstr GFS2: make sure S_NOSEC flag isn't overwritten GFS2: add support for rename2 and RENAME_EXCHANGE gfs2: handle NULL rgd in set_rgrp_preferences GFS2: inode.c: indent with TABs, not spaces GFS2: mark the journal idle to fix ro mounts GFS2: Average in only non-zero round-trip times for congestion stats GFS2: Use average srttb value in congestion calculations

gfs2: Don't support fallocate on jdata files

We cannot provide an efficient implementation due to the headers on the data blocks, so there doesn't seem much point in having it. Signed-off-by: Abhi Das Signed-off-by: Bob Peterson

GFS2: make sure S_NOSEC flag isn't overwritten

2015-05-05T17:25:48+00:00

At the end of gfs2_set_inode_flags inode->i_flags is set to flags, so we should be modifying flags instead of inode->i_flags, so it isn't overwritten. Signed-off-by: Benjamin Marzinski Signed-off-by: Bob Peterson

make new_sync_{read,write}() static

All places outside of core VFS that checked ->read and ->write for being NULL or called the methods directly are gone now, so NULL {read,write} with non-NULL {read,write}_iter will do the right thing in all cases. Signed-off-by: Al Viro

gfs2: allow fallocate to max out quotas/fs efficiently

2015-03-18T17:48:02+00:00

We can quickly get an estimate of how many blocks are available for allocation restricted by quota and fs size respectively, using the ap->allowed field in the gfs2_alloc_parms structure. gfs2_quota_check() and gfs2_inplace_reserve() provide these values. Once we have the total number of blocks available to us, we can compute how many bytes of data can be written using those blocks instead of guessing inefficiently.
