[libc-commits] [PATCH] D153571: [libc] Add memory fences to device-local locking calls

[Jon Chesterfield via Phabricator via libc-commits]

JonChesterfield added inline comments.


================
Comment at: libc/src/__support/RPC/rpc.h:531
     uint64_t lane_mask = gpu::get_lane_mask();
-    // Attempt to acquire the lock on this index.
     if (!this->try_lock(lane_mask, index))
----------------

Writing the comment out twice seems excessive. This makes this code match the copy&paste in the other class too.
