Currently, it is not possible to determine for sure if a reader owns a rwsem by looking at the content of the rwsem data structure. This patch adds a new state RWSEM_READER_OWNED to the owner field to indicate that readers currently own the lock. This enables us to address the following 2 issues

Without using WRITE_ONCE(), the compiler can potentially break a write into multiple smaller ones (store tearing). So a read from the same data by another task concurrently may return a partial result. This can result in a kernel crash if the data is a memory address that is being dereferenced.
