ck_swlock: A single writer rwlock.
...
This lock is copy-safe when the latch operations are used.
Simplified write side operations lead to lower latencies than ck_rwlock
for single writer workloads.

ck_rwlock: Migrate to 32-bit primitives and add a write_latch operation.
...
write_latch allows writers to prevent incoming read acquisitions from
succeeding while permitting write_lock operations to complete. This is
useful if multiple writers are cooperating in linearizing a non-blocking
data structure and allows for lock state to be copied by the write lock
holder safely.
In collaboration with Paul Khuong and Jaidev Sridhar.
