[PATCH v2 0/4] sunrpc: cache infrastructure scalability improvements

[Jeff Layton <jlayton@kernel.org>]

The first patch fixes a pre-existing bug that Neil spotted during the
review of v1. The next two patches convert the global spinlock and
waitqueue to be per-cache_detail instead.

The last patch splits up the cache_detail->queue into two lists: one to
hold cache_readers and one for cache_requests. This simplifies the code,
and the new sequence number that helps the readers track position may
help with implementing netlink upcalls.

Please consider these for v7.1.
