class BrwLock

Defined at line 97 of file ../../zircon/kernel/include/kernel/brwlock.h

Blocking (i.e. non spinning) reader-writer lock. Readers and writers are

ordered by priority (i.e. their wait_queue release order) and otherwise

readers and writers are treated equally and will fall back to FIFO ordering

at some priority.

The lock optionally respects priority inheritance. Not supporting PI is more

efficient as the current active writer does not have to be tracked. Enabling PI

creates an additional restriction that readers must not take any additional

locks or otherwise block whilst holding the read lock.
