| * nilfs2: get rid of bd_mount_sem use from nilfsRyusuke Konishi2009-06-114-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | This will remove every bd_mount_sem use in nilfs. The intended exclusion control was replaced by the previous patch ("nilfs2: correct exclusion control in nilfs_remount function") for nilfs_remount(), and this patch will replace remains with a new mutex that this inserts in nilfs object.

| * nilfs2: correct exclusion control in nilfs_remount functionRyusuke Konishi2009-06-113-31/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nilfs_remount() changes mount state of a superblock instance. Even though nilfs accesses other superblock instances during mount or remount, the mount state was not properly protected in nilfs_remount(). Moreover, nilfs_remount() has a lock order reversal problem; nilfs_get_sb() holds: 1. bdev->bd_mount_sem 2. sb->s_umount (sget acquires) and nilfs_remount() holds: 1. sb->s_umount (locked by the caller in vfs) 2. bdev->bd_mount_sem To avoid these problems, this patch divides a semaphore protecting super block instances from nilfs->ns_sem, and applies it to the mount state protection in nilfs_remount(). With this change, bd_mount_sem use is removed from nilfs_remount() and the lock order reversal will be resolved. And the new rw-semaphore, nilfs->ns_super_sem will properly protect the mount state except the modification from nilfs_error function.

| * nilfs2: simplify remaining sget() useRyusuke Konishi2009-06-114-25/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies the test function passed on the remaining sget() callsite in nilfs. Instead of checking mount type (i.e. ro-mount/rw-mount/snapshot mount) in the test function passed to sget(), this patch first looks up the nilfs_sb_info struct which the given mount type matches, and then acquires the super block instance holding the nilfs_sb_info.

| * nilfs2: get rid of sget use for checking if current mount is presentRyusuke Konishi2009-06-112-60/+35
| | | | | | | | | | | | | | | | | | | | This stops using sget() for checking if an r/w-mount or an r/o-mount exists on the device. This elimination uses a back pointer to the current mount added to nilfs object.

| * nilfs2: get rid of sget use for acquiring nilfs objectRyusuke Konishi2009-06-113-65/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This will change the way to obtain nilfs object in nilfs_get_sb() function. Previously, a preliminary sget() call was performed, and the nilfs object was acquired from a super block instance found by the sget() call. This patch, instead, instroduces a new dedicated function find_or_create_nilfs(); as the name implies, the function finds an existent nilfs object from a global list or creates a new one if no object is found on the device.

| * nilfs2: remove meaningless EBUSY case from nilfs_get_sb functionRyusuke Konishi2009-06-111-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following EBUSY case in nilfs_get_sb() is meaningless. Indeed, this error code is never returned to the caller. if (!s->s_root) { ... } else if (!(s->s_flags & MS_RDONLY)) { err = -EBUSY; } This simply removes the else case.

| * remove the call to ->write_super in __sync_filesystemChristoph Hellwig2009-06-111-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | Now that all filesystems provide ->sync_fs methods we can change __sync_filesystem to only call ->sync_fs. This gives us a clear separation between periodic writeouts which are driven by ->write_super and data integrity syncs that go through ->sync_fs.

| * fs: block_dump missing dentry lockingNick Piggin2009-06-111-17/+24
| | | | | | | | | | | | | | | | | | I think the block_dump output in __mark_inode_dirty is missing dentry locking. Surely the i_dentry list can change any time, so we may not even *get* a dentry there. If we do get one by chance, then it would appear to be able to go away or get renamed at any time...

| * fs: remove incorrect I_NEW warningsNick Piggin2009-06-111-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some filesystems can call in to sync an inode that is still in the I_NEW state (eg. ext family, when mounted with -osync). This is OK because the filesystem has sole access to the new inode, so it can modify i_state without races (because no other thread should be modifying it, by definition of I_NEW). Ie. a false positive, so remove the warnings. The races are described here 7ef0d7377cb287e08f3ae94cebc919448e1f5dff, which is also where the warnings were introduced.
