NFSv4.2: Rework scratch handling for READ_PLUS
...
[ Upstream commit fbd2a05f29 ]
Instead of using a tiny, static scratch buffer, we should use a kmalloc()-ed
buffer that is allocated when checking for read plus usage. This lets us
use the buffer before decoding any part of the READ_PLUS operation
instead of setting it right before segment decoding, meaning it should
be a little more robust.
