NFS: remove support for multi-segment iovs in the direct write path
Eliminate the persistent use of automatic storage in all parts of the
NFS client's direct write path to pave the way for introducing support
for aio against files opened with the O_DIRECT flag.
NACK. We have patches pending that consolidate ->aio_read/write and
->read/writev into one operation. this change is completely counterproductive
towards that goal which has been discussed on -fsdevel for a while.
and when do you expect these changes to be integrated? we've had this
implementation for almost a year, and zach brown has reviewed it. we
discussed the aio_read/readv change with him and he agreed that this
should go in now.
we have major customers who are demanding this functionality now, and
can support the reimplementation whenever you guys get your aio act
together.
