Description
For example, there are many places in the emerging VFS layer that can benefit from the read-mostly situation and synchronization offered by readers-writer locks.
There is a non-starving implementation of rwlocks in the kernel, but it heavily interacts with the wait queue mechanism and is not suitable for uspace. A more lightweight implementation based on futexes should be created.
