gfs2: use workqueue instead of slow-work Workqueue can now handle high concurrency. Convert gfs to use workqueue instead of slow-work. * Steven pointed out that recovery path might be run from allocation path and thus requires forward progress guarantee without memory allocation. Create and use gfs_recovery_wq with rescuer. Please note that forward progress wasn't guaranteed with slow-work. * Updated to use non-reentrant workqueue.

gfs2: clean_journal improperly set sd_log_flush_head This patch fixes regressions in 588bff95c94efc05f9e1a0b19015c9408ed7c0ef. Due to that patch, function clean_journal was setting the value of sd_log_flush_head, but that's only valid if it is replaying the node's own journal. If it's replaying another node's journal, that's completely wrong and will lead to multiple problems. This patch tries to clean up the mess by passing the value of the logical journal block number into gfs2_write_log_header so the function can treat non-owned journals generically. For the local journal, the journal extent map is used for best performance. For other nodes from other journals, new function gfs2_lblk_to_dblk is called to figure it out using gfs2_iomap_get. This patch also tries to establish more consistency when passing journal block parameters by changing several unsigned int types to a consistent u32.

GFS2: Fix gfs2_replay_incr_blk for multiple journal sizes Before this patch, if you used gfs2_jadd to add new journals of a size smaller than the existing journals, replaying those new journals would withdraw. That's because function gfs2_replay_incr_blk was using the number of journal blocks (jd_block) from the superblock's journal pointer. In other words, "My journal's max size" rather than "the journal we're replaying's size." This patch changes the function to use the size of the pertinent journal rather than always using the journal we happen to be using. Signed-off-by: Bob Peterson <rpeterso@redhat.com>

gfs2: No longer use 'extern' in function declarations For non-static function declarations, external linkage is implied and the 'extern' keyword isn't needed. Some static checkers complain about the overuse of 'extern', so clean up all the function declarations. In addition, remove 'extern' from the definition of free_local_statfs_inodes(); it isn't needed there, either. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com>
