Commit https://github.com/torvalds/linux/commit/94a9717b updated the rwsem's owner field to contain additional flags describing the rwsem's state. Rather then update the wrappers to mask out these bits, the code no longer relies on the owner stored by the kernel. This does increase the size of a krwlock_t but it makes the implementation less sensitive to future kernel changes.
