This takes in the comment and replaces the use of GFP_NOWAIT flag with
GFP_NOIO.

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.

This fixes disorder of nilfs_write_super in nilfs_sync_fs. Commiting
super block must be the end of the function so that every changes are
reflected.
->sync_fs() is not called frequently so this makes nilfs_sync_fs call
nilfs_commit_super instead of nilfs_write_super.

This removes redundant super block commit.
nilfs_write_super will call nilfs_commit_super to store super block
into block device. However, nilfs_put_super will call
nilfs_commit_super right after calling nilfs_write_super. So calling
nilfs_write_super in nilfs_put_super would be redundant.

The current metadata file code skips disk address lookup for its data
block if the buffer has a mapped flag.
This has a potential risk to cause read request to be performed
against the stale block address that GC moved, and it may lead to meta
data corruption. The mapped flag is safe if the buffer has an
uptodate flag, otherwise it may prevent necessary update of disk
address in the next read.
This will avoid the potential problem by ensuring disk address lookup
before reading metadata block even for buffers with the mapped flag.

blk_ioctl_discard duplicates large amounts of code from blkdev_issue_discard,
the only difference between the two is that blkdev_issue_discard needs to
send a barrier discard request and blk_ioctl_discard a non-barrier one,
and blk_ioctl_discard needs to wait on the request. To facilitates this
add a flags argument to blkdev_issue_discard to control both aspects of the
behaviour. This will be very useful later on for using the waiting
funcitonality for other callers.

This fixes up broken clock re-parenting undertaken by the SH7709 clock
framework code, which is currently in conflict with the legacy CPG
framework. With this change in place, the legacy CPG ancestry is used,
and we manage to avoid contending on the clock_list_sem mutex, which is
already held under the legacy registration path, resulting in livelock.
In order for SH7709 to fully support the varying clock modes, it needs to
implement a more complete clock framework. After this change it is in
sync with legacy CPG mode, which ends up being the default configuration
for this CPU anyways.
