If a wait queue is defined as a "priority queue" then requests are dequeued
in blocks of 16 in order to work well with write gathering + readahead on the
server.
There are 3 levels of priority. The high priority tasks get scheduled 16 times
for each time the default level gets scheduled. The lowest level gets
scheduled once every 4 times the normal level gets scheduled.

RPC: remove unnecessary support for sk->sk_sleep on those sockets that are

We default to "long" (which is what POSIX says), but since
a number of architectures have used "int" for historical
reasons, we need to allow overrides.

At least sparc64 needs this. Possibly others, but so far
architecture maintainers haven't spoken up. ppc64 and x86-64
are known to be ok with the default "long".
