This is also the value used also for generic

The values below are x86-specific; the actual defines are arch-dependent.
Do other archs use different values?
This is also the value used also for generic case. I

It takes me a while to understand how rwsem's count field mainifest
itself in different scenarios. I'm adding comments to provide a quick
reference on the the rwsem's count field for each scenario where readers
and writers are contending/holding the lock. Hopefully it will be useful
for future
