Merge patch series "netfs: Miscellaneous fixes"

Browse Source 
David Howells <dhowells@redhat.com> says:

Here are some miscellaneous fixes and changes for netfslib, if you could
pull them:

 (1) Fix an oops in write-retry due to mis-resetting the I/O iterator.

 (2) Fix the recording of transferred bytes for short DIO reads.

 (3) Fix a request's work item to not require a reference, thereby avoiding
     the need to get rid of it in BH/IRQ context.

 (4) Fix waiting and waking to be consistent about the waitqueue used.
