In blocklayout driver. There are two things happening
while layoutcommit/cleanup.
1. the modified extents are encoded.
2. On cleanup the extents are put back on the layout rw
extents list, for reads.
In the new system where actual xdr encoding is done in
encode_layoutcommit() directly into xdr buffer, these are
the new commit stages:
1. On setup_layoutcommit, the range is adjusted as before
and a structure is allocated for communication with
bl_encode_layoutcommit && bl_cleanup_layoutcommit
(Generic layer provides a void-star to hang it on)
2. bl_encode_layoutcommit is called to do the actual
encoding directly into xdr. The commit-extent-list is not
freed and is stored on above structure.
FIXME: The code is not yet converted to the new XDR cleanup
3. On cleanup the commit-extent-list is put back by a call
to set_to_rw() as before, but with no need for XDR decoding
of the list as before. And the commit-extent-list is freed.
Finally allocated structure is freed.

This fixes a soft lockup on conditions
a) the flusher is working on a work by __bdi_start_writeback(), while
b) someone else calls writeback_inodes_sb*() or sync_inodes_sb(), which
grab sb->s_umount and enqueue a new work for the flusher to execute
The s_umount grabbed by (b) will fail the grab_super_passive() in (a).
Then if the inode is requeued, wb_writeback() will busy retry on it.
As a result, wb_writeback() loops for ever without releasing
wb->list_lock, which further blocks other tasks.
Fix the busy loop by redirtying the inode. This may undesirably delay
the writeback of the inode, however most likely it will be picked up
soon by the queued work by writeback_inodes_sb*(), sync_inodes_sb() or
even writeback_inodes_wb().

rc unregister logic were deadly broken, preventing some drivers to
be removed. Among the broken things, rc_dev_uevent() is being called
during device_del(), causing a data filling on an area that it is
not ready anymore.
Also, some drivers have a stop callback defined, that needs to be called
before data removal, as it stops data polling.
