OK, looking at these patches closely, can you +1
and add your 'Reviewed-by:' to the first of the
two patches - that's the one that only fixes
the non-splice recvfile (the read/write path
in TRANSFER_BUF_SIZE (128*1024) chunks)
to work correctly with a non-blocking
That single fix (attached) is independent
of the splice() code changes, and can
be pushed independently. It would be good
to get this in, as it allows people to
turn on recvfile in SMB2 without needing
a working splice and I'll work on the splice
