The unlatch operation now just unsets the latch bit, we can safely decrement n_readers in ck_swlock_read_latchlocks(). + Fixes to validation tests & ELIDE coverage.	11 years ago

ck_swlock: We shouldn't decrement n_readers when

ck_swlock_read_latchlocks observers a writer if the unlatch
operation sets n_readers to 0.

The unlatch operation now just unsets the latch bit, we can safely
decrement n_readers in ck_swlock_read_latchlocks().

+ Fixes to validation tests & ELIDE coverage.

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.
