There are three different strategies to uniquely identify a futex in the
kernel:
- Private futexes: uses the pointer to mm_struct and the page address
- Shared futexes: checks if the page containing the address is a PageAnon:
- If it is, uses the same data as a private futexes
- If it isn't, uses an inode sequence number from struct inode and
the page's index
Create a selftest to check those three paths and basic wait/wake
mechanism.
