gfs2: Make gfs2_write_full_page static (2017-02-03 08:23:47 -0500)
---------------------------------------------------------------- We've got eight GFS2 patches for this merge window:
1. Andy Price submitted a patch to make gfs2_write_full_page a static function. 2. Dan Carpenter submitted a patch to fix a ERR_PTR thinko.
I've also got a few patches, three of which fix bugs related to deleting very large files, which cause GFS2 to run out of journal space:
3. The first one prevents GFS2 delete operation from requesting too much journal space. 4. The second one fixes a problem whereby GFS2 can hang because it wasn't taking journal space demand into its calculations. 5. The third one wakes up IO waiters when a flush is done to restart processes stuck waiting for journal space to become available.
The other three patches are a performance improvement related to spin_lock contention between multiple writers:
6. The "tr_touched" variable was switched to a flag to be more atomic and eliminate the possibility of some races. 7. Function meta_lo_add was moved inline with its only caller to make the code more readable and efficient. 8. Contention on the gfs2_log_lock spinlock was greatly reduced by avoiding the lock altogether in cases where we don't really need it: buffers that already appear in the appropriate metadata list for the journal. Many thanks to Steve Whitehouse for the ideas and principles behind these patches.
