# Platform-specific glue layers go here
#
# NOTICE: Make sure your glue layer doesn't depend on anything
# which is arch-specific and that it compiles on all situations.
#
# We want to keep this requirement in order to be able to compile
# the entire driver (with all its glue layers) on several architectures
# and make sure it compiles fine. This will also help with allmodconfig
# and allyesconfig builds.

under the waitqueue lock. It may be set when there are no tasks on the waitqueue, which will cause a harmless extra wakeup check that will clears the bit. The generic bit-waitqueue infrastructure is no longer used for pages. Instead, waitqueues are used directly with a custom key type. The generic code was not flexible enough to have PageWaiters manipulation under the waitqueue lock (which simplifies concurrency). This improves the performance of page lock intensive microbenchmarks by 2-3%. Putting two bits in the same word opens the opportunity to remove the memory barrier between clearing the lock bit and testing the waiters bit, after some work on the arch primitives (e.g., ensuring memory operand widths match and cover both bits).
