pnfs: support for non-rpc layout drivers
Non-rpc layout driver such as for objects and blocks implement their own I/O path and error handling logic. Therefore bypass NFS-based error handling for these layout drivers. [fix lseg ref-count bugs, and null de-refs] [Fall out from: non-rpc layout drivers] Signed-off-by: Boaz Harrosh <bharrosh@panasas.com> [get rid of PNFS_USE_RPC_CODE] [get rid of __nfs4_write_done_cb] [revert useless change in nfs4_write_done_cb] Signed-off-by: Benny Halevy <bhalevy@panasas.com>
