* ext3: Avoid loading bitmaps for full groups during block allocationFrans van de Wiel2010-05-211-0/+6
| | | | | | | | | | | | There is no point in loading bitmap for groups which are completely full. This causes noticeable performance problems (and memory pressure) on small systems with large full filesystem (http://marc.info/?l=linux-ext4&m=126843108314310&w=2).

* Fix networking tree iscsi_tcp.c mis-mergeLinus Torvalds2010-05-211-1/+1
| | | | | | | | | | | | | | | The removal of the 'waitqueue_active()' test in commit d7d05548a6 ("[SCSI] iscsi_tcp: fix relogin/shutdown hang") got incorrectly resolved by David when he back-merged the main git tree into the networking tree in commit 278554bd65 ("Merge branch 'master' of master.kernel.org:..."). There was a content conflict due to 'sock->sk->sk_sleep' being changed into 'sk_sleep(sock->sk)' in the networking tree, but David didn't pick up the iscsi change from the main tree.

| * nilfs2: disallow remount of snapshot from/to a regular mountRyusuke Konishi2010-05-101-34/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Snapshots and regular ro/rw mounts are essentially-different within the meaning whether the checkpoint is static or not and is marked with a snapshot flag or not. The current implemenation, however, allows to remount a snapshot to a regular rw-mount if the checkpoint number equals the latest one. This transition is actually impossible since changing a checkpoint to a snapshot makes another checkpoint, thus the condition is never satisfied. This fixes the weird state of affairs, and specifically separates snapshots and regular rw/ro-mounts. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

| * nilfs2: enlarge s_volume_name member in nilfs_super_blockJiro SEKIBA2010-05-101-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current s_volume_name has 16 bytes, which is too small as modern filesystem. s_last_mounted resides just after s_volume_name and has 64 bytes. s_last_mounted is historically came from ext2, but not used in nilfs2 at all. Deleting s_last_mounted member and merging that space with s_volume_name enlarge s_volume_name upto 80 bytes for volume label. When user land tools see the old header for new disk, it will just ignore additional bytes stored in s_last_mounted. While, old disk format has only 16 bytes label, it doesn't affects in case seeing the new header for old disk.

| * nilfs2: use checkpoint number instead of timestamp to select super blockRyusuke Konishi2010-05-101-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nilfs maintains two super blocks, and selects the new one on mount time if they both have valid checksums and their timestamps differ. However, this has potential for mis-selection since the system clock may be rewinded and the resolution of the timestamps is not high. Usually this doesn't become an issue because both super blocks are updated at the same time when the file system is unmounted. Even if the file system wasn't unmounted cleanly, the roll-forward recovery will find the proper log which stores the latest super root. Thus, the issue can appear only if update of one super block fails and the clock happens to be rewinded. This fixes the issue by using checkpoint numbers instead of timestamps to pick the super block storing the location of the latest log. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
| * nilfs2: add missing endian conversion on super block magic numberRyusuke Konishi2010-05-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | This adds missing endian conversions in comparision of the magic number of super blocks. It was coincidence that prior versions didn't incur problems; the upper byte of the magic number happened to be equal to the lower byte. But, semantically it's wrong to depend on this. This won't change anything else nor suffer any compatibility issues. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

| | | | | | | | | | | | | | | | | | | | | | | | There are only two lines of code in nilfs_segctor_init(). From a logic design view, the first line 'sci->sc_seq_done = sci->sc_seq_request;' should be put in nilfs_segctor_new(). Even in nilfs_segctor_new(), this initialization is needless because sci is kzalloc-ed. So nilfs_segctor_init() is only a wrap call to nilfs_segctor_start_thread().

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * | | | mtd: mxc_nand: Remove duplicate NAND_CMD_RESET case valueDavid Woodhouse2010-05-201-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 66803762 ("mtd: mxc_nand: add RESET command support"). Support for NAND_CMD_RESET was added separately in commit d4840180 ("mtd: mxc_nand: set NFC registers after reset"), causing a build error: drivers/mtd/nand/mxc_nand.c: In function 'mxc_nand_command': drivers/mtd/nand/mxc_nand.c:689: error: duplicate case value drivers/mtd/nand/mxc_nand.c:606: error: previously used here Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

| * | | | jffs2: Stop triggering block erases from jffs2_write_super()Joakim Tjernlund2010-05-191-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | | jffs2: Rename jffs2_erase_pending_trigger() to jffs2_dirty_trigger()Joakim Tjernlund2010-05-192-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we do erases from GC and trigger the GC thread to do them instead of using kupdated, this function is misnamed. It's only used for triggering wbuf flush on NAND flash now. Rename it accordingly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is now done in a GC pass; we don't need to trigger kupdated to do it. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We're about to call this from a bunch of places which already hold c->erase_completion_lock, so add an assertion and change its existing callers to do the same. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
