These bug fixes for the pnfs block layout driver should apply to linux 3.1.

Jim Rees (2):
  pnfsblock: fix size of upcall message
  pnfsblock: fix return code confusion

Peng Tao (3):
  pnfsblock: fix NULL pointer dereference
  pnfsblock: fix writeback deadlock
  pnfsblock: add missing rpc_put_mount and path_put

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."

Always return PTR_ERR, not NULL, from nfs4_blk_get_deviceinfo and
nfs4_blk_decode_device.

Check for IS_ERR, not NULL, in bl_set_layoutdriver when calling
nfs4_blk_get_deviceinfo.

bl_add_page_to_bio returns error pointer. bio should be reset to
NULL in failure cases as the out path always calls bl_submit_bio.

We should check if the sector is already initialized before
trying to grab the page from page cache. Otherwise when two
pages of the same block are written back by two threads each
calling from writepage_locked, it can cause deadlock like bellow.
