An fmode_t argument is passed to kill_block_super() through s_mode member of the super_block structure. This is used to release the block device with the same mode, however, nilfs does not set s_mode anywhere. This modifies nilfs_get_sb function to properly initialize the s_mode member.

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: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

Like ext3, nilfs has 'errors' mount option to allow specifying desired behavior on severe errors. Currently, the default action is 'errors=continue' and has potential to advance filesystem corruption for severe errors. This will change the action to 'errors=remount-ro' to avoid the issue.

As of 32a88aa1, __sync_filesystem() will return 0 if s_bdi is not set. And nilfs does not set s_bdi anywhere.

This replaces s_dirt flag use in nilfs with a new flag added on the nilfs object. The s_dirt flag was used to indicate if sop->write_super() should be called, however the current version of nilfs does not use the callback. Thus, it can be replaced with the own flag.

nilfs_error() calls nilfs_detach_segment_constructor() if errors=remount-ro option is specified, and this may lead to a hang due to recursive locking of, for instance, nilfs->ns_segctor_sem and others. In this case, detaching segment constructor is not necessary because read-only flag is set to the filesystem and further writes are blocked. This fixes the potential hang issue by removing the nilfs_detach_segment_constructor() call from nilfs_error. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

This adds "norecovery" mount option which disables temporal write access to read-only mounts or snapshots during mount/recovery. Without this option, write access will be even performed for those types of mounts; the temporal write access is needed to mount root file system read-only after an unclean shutdown. This option will be helpful when user wants to prevent any write access to the device. Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp> Cc: Eric Sandeen <sandeen@redhat.com>

Although mount recovery of nilfs is integrated in load_nilfs() procedure, the completion of recovery was isolated from the procedure and performed at the end of the fill_super routine. This was somewhat confusing since the recovery is needed for the nilfs object, not for a super block instance. To resolve the inconsistency, this will integrate the recovery completion into load_nilfs(). Signed-off-by: NRyusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

This removes nilfs_write_super and commit super block in nilfs internal thread, instead of periodic write_super callback. VFS layer calls ->write_super callback periodically. However, it looks like that calling back is ommited when disk I/O is busy. And when cleanerd (nilfs GC) is runnig, disk I/O tend to be busy thus nilfs superblock is not synchronized as nilfs designed. To avoid it, syncing superblock by nilfs thread instead of pdflush.

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.

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.

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.
