| | * UBIFS: remove fast unmountingArtem Bityutskiy2009-01-292-47/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This UBIFS feature has never worked properly, and it was a mistake to add it because we simply have no use-cases. So, lets still accept the fast_unmount mount option, but ignore it. This does not change much, because UBIFS commit in sync_fs anyway, and sync_fs is called while unmounting.

| | * UBIFS: return sensible error codesArtem Bityutskiy2009-01-292-9/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When mounting/re-mounting, UBIFS returns EINVAL even if the ENOSPC or EROFS codes are are much better, just because we have not found references to ENOSPC/EROFS in mount (2) man pages. This patch changes this behaviour and makes UBIFS return real error code, because: 1. It is just less confusing and more logical 2. mount is not described in SuSv3, so it seems to be not really well-standartized 3. we do not cover all cases, and any random undocumented in man pages error code may be returned anyway Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

| | * UBIFS: fix no_chk_data_crcArtem Bityutskiy2009-01-273-13/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When data CRC checking is disabled, UBIFS returns incorrect return code from the 'try_read_node()' function (0 instead of 1, which means CRC error), which make the caller re-read the data node again, but using a different code patch, so the second read is fine. Thus, we read the same node twice. And the result of this is that UBIFS is slower with no_chk_data_crc option than it is with chk_data_crc option. This patches fixes the problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When mounting read-only the orphan area head is not initialized. It must be initialized when remounting read/write, but it was not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we mount UBIFS, GC LEB may contain out-of-date information, and UBIFS should update lprops and set free space for thei LEB. Currently UBIFS does this only if mounted R/W. But for R/O mount we have to do the same, because otherwise we will have incorrect FS free space reported to user-space.

This message tells that node to first cancel convert the upconvert request, followed by downconvert to a NL. Only when this lock is downconverted to NL, can the master upconvert the first node's lock to EX. While the fs was doing the cancel convert, it was forgetting to wake up the dc thread after a successful cancel, leading to a deadlock.

It has a potential problem that it may let the already-accessed-but-not-dirtied buffers gone. So we'd better access the bucket after we call ocfs2_xattr_value_truncate.

| | * | configfs: Silence lockdep on mkdir(), rmdir() and configfs_depend_item()Joel Becker2009-02-021-0/+59

This is needed to ensure that the VFS will not race with operations on these sub-dirs. This is safe for the following reasons: - the VFS allows one to lock first an inode and second one of its children (The lock subclasses for this pattern are respectively I_MUTEX_PARENT and I_MUTEX_CHILD); - from this rule any inode path can be recursively locked in descending order as long as it stays under a single mountpoint and does not follow symlinks. Unfortunately lockdep does not know (yet?) how to handle such recursion. I've tried to use Peter Zijlstra's lock_set_subclass() helper to upgrade i_mutexes from I_MUTEX_CHILD to I_MUTEX_PARENT when we know that we might recursively lock some of their descendant, but this usage does not seem to fit the purpose of lock_set_subclass() because it leads to several i_mutex locked with subclass I_MUTEX_PARENT by the same task. >From inside configfs it is not possible to serialize those recursive locking with a top-level one, because mkdir() and rmdir() are already called with inodes locked by the VFS. So using some mutex_lock_nest_lock() is not an option. I am proposing two solutions: 1) one that wraps recursive mutex_lock()s with lockdep_off()/lockdep_on(). 2) (as suggested earlier by Peter Zijlstra) one that puts the i_mutexes recursively locked in different classes based on their depth from the top-level config_group created. This induces an arbitrary limit (MAX_LOCK_DEPTH - 2 == 46) on the nesting of configfs default groups whenever lockdep is activated but this limit looks reasonably high. Unfortunately, this alos isolates VFS operations on configfs default groups from the others and thus lowers the chances to detect locking issues. This patch implements solution 1). Solution 2) looks better from lockdep's point of view, but fails with configfs_depend_item(). This needs to rework the locking scheme of configfs_depend_item() by removing the variable lock recursion depth, and I think that it's doable thanks to the configfs_dirent_lock. For now, let's stick to solution 1). Signed-off-by: Louis Rilling <louis.rilling@kerlabs.com> Acked-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It could happen that some limit has been set via quotactl() and in parallel ->mark_dirty() is called from another thread doing e.g. dquot_alloc_space(). In such case ocfs2_write_dquot() must not try to sync the dquot because that needs global quota lock but that ranks above transaction start.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dropping of last reference to dentry lock is a complicated operation involving dropping of reference to inode. This can get complicated and quota code in particular needs to obtain some quota locks which leads to potential deadlock. Thus we defer dropping of inode reference to ocfs2_wq.

This caused running the filefrag program (which uses the FIMBAP ioctl) to trigger a BUG(). The EXT4_STATE_JDATA bit is only used for ext4_bmap(), and it's harmless for the bit to be set. We could add a check in __ext4_journalled_writepage() and ext4_journalled_write_end() to only set the EXT4_STATE_JDATA bit if the journal is present, but that adds an extra test and jump instruction.
