As discussed earlier, it is better for block client to allocate memory for
tracking extents state before submitting bio. So the patch does it by allocating
a short_extent for every INVALID extent touched by write pagelist and for
every zeroing page we created, saving them in layout header. Then in end_io we
can just use them to create commit list items and avoid memory allocation there.Signed-off-by: Peng Tao

Make the status field explicitly 32 bits. "...it's unlikely that the kernel
and userspace would differ on the size of an int here, but it might be a
good idea to go ahead and make that explicitly 32 bits in case we end up
dealing with more exotic arches at some point in the future."Suggested-by: Jeff Layton

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 cleanup3. 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.[rm inode and pnfs_layout_hdr args from cleanup_layoutcommit()]
