    nilfs2: get rid of bd_mount_sem use from nilfs

    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 function

    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() use

    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 present

    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 object

    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 function

    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.

  13. remove the call to ->write_super in __sync_filesystem

    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. (modulo file_fsync which is also going away)
