| * GFS2: Fix writing to non-page aligned gfs2_quota structuresAbhijith Das2010-05-101-25/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the upstream fix for this bug. This patch differs from the RHEL5 fix (Red Hat bz #555754) which simply writes to the 8-byte value field of the quota. In upstream quota code, we're required to write the entire quota (88 bytes) which can be split across a page boundary. We check for such quotas, and read/write the two parts from/to the corresponding pages holding these parts. With this patch, I don't see the bug anymore using the reproducer in Red Hat bz 555754. I successfully ran a couple of simple tests/mounts/ umounts and it doesn't seem like this patch breaks anything else.

| * GFS2: Add some useful messagesSteven Whitehouse2010-05-064-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | The following patch adds a message to indicate when barriers have been disabled due to a block device which doesn't support them. You could already tell this via the mount options in /proc/mounts, but all the other filesystems also log a message at the same time. Also, the same mechanisms are used to indicate when the lock demote interface has been used (only ever used for debugging) which is a request from our support team.

| * GFS2: Various gfs2_logd improvementsBenjamin Marzinski2010-05-059-92/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch contains various tweaks to how log flushes and active item writeback work. gfs2_logd is now managed by a waitqueue, and gfs2_log_reseve now waits for gfs2_logd to do the log flushing. Multiple functions were rewritten to remove the need to call gfs2_log_lock(). Instead of using one test to see if gfs2_logd had work to do, there are now seperate tests to check if there are two many buffers in the incore log or if there are two many items on the active items list. This patch is a port of a patch Steve Whitehouse wrote about a year ago, with some minor changes. Since gfs2_ail1_start always submits all the active items, it no longer needs to keep track of the first ai submitted, so this has been removed. In gfs2_log_reserve(), the order of the calls to prepare_to_wait_exclusive() and wake_up() when firing off the logd thread has been switched. If it called wake_up first there was a small window for a race, where logd could run and return before gfs2_log_reserve was ready to get woken up. If gfs2_logd ran, but did not free up enough blocks, gfs2_log_reserve() would be left waiting for gfs2_logd to eventualy run because it timed out. Finally, gt_logd_secs, which controls how long to wait before gfs2_logd times out, and flushes the log, can now be set on mount with ar_commit.

| * GFS2: glock livelockBob Peterson2010-04-147-29/+144
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a couple gfs2 problems with the reclaiming of unlinked dinodes. First, there were a couple of livelocks where everything would come to a halt waiting for a glock that was seemingly held by a process that no longer existed. In fact, the process did exist, it just had the wrong pid number in the holder information. Second, there was a lock ordering problem between inode locking and glock locking. Third, glock/inode contention could sometimes cause inodes to be improperly marked invalid by iget_failed. Signed-off-by: Bob Peterson <rpeterso@redhat.com>
| * GFS2: Clean up stuffed file copyingSteven Whitehouse2010-03-292-10/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | If the inode size was corrupt for stuffed files, it was possible for the copying of data to overrun the block and/or page. This patch checks for that condition so that this is no longer possible. This is also preparation for the new truncate sequence patch which requires the ability to have stuffed files with larger sizes than (disk block size - sizeof(on disk inode)) with the restriction that only the initial part of the file may be non-zero.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the culmination of this sequence of patches. By moving the block erasing from jffs2_write_super() into the GC code, we avoid huge latencies on unmount where it waits for _all_ pending blocks to be erased, and we allow better control for time-critical tasks by stopping the GC thread.

We only use the second routine if we know we only have that log item chunk, so get rid of the limited routine and always use the more complete one. Also rename the old xfs_trans_buf_item_match_all to xfs_trans_buf_item_match and update various surrounding comments, and move the remaining xfs_trans_buf_item_match on top of the file to avoid a forward prototype.

But as the commit 97db39a1f6f69e906e98118392400de5217aa33a has changed bmv_count to the caller's input buffer, this number query function can't work any more. As this commit is written to change bmv_count from MAXEXTNUM because of ENOMEM. This patch just try to set bm.bmv_count to something sane.

The name was chosen for consistency with the other fields in the structure that represent a number of basic blocks. (Updated so that a variable used in computing and verifying a log's sector size is named "log2_size". Also added the "BB" to the structure field name, based on feedback from Eric Sandeen. Also dropped some superfluous parentheses.) Signed-off-by: Alex Elder <aelder@sgi.com> Reviewed-by: Eric Sandeen <sandeen@sandeen.net>
