v4->v5: - Add a new patch to rename function names to sync up to qspinlock naming convention. - Move the extended qrwlock structure to the header file as requested by Will Deacon so that it can also be used in the ARM's architecture specific code.
v3->v4: - Remove the unnecessary _QW_WMASK check in queue_read_lock_slowpath().
v2->v3: - Fix incorrect commit log message in patch 1.
v1->v2: - Add microbenchmark data for the second patch
This patch set contains 2 patches on qrwlock. The first one is to optimize the interrupt context reader slowpath. The second one is to optimize the writer slowpath.
*** BLURB HERE ***
Waiman Long (3): locking/qrwlock: Rename functions to queued_*() locking/qrwlock: Better optimization for interrupt context readers locking/qrwlock: Don't contend with readers when setting _QW_WAITING
