| |
Hi,
During my last PI failing patch set it became obvious there's a number of related fail in FUTEX_UNLOCK_PI that needed sorting before we can move on with that stuff.
These here patches are the result of staring at that code for a wee bit.
Please have a very _very_ careful look at the last patch, it appears to not explode when running:
- perf bench futex lock-pi - selftests/futex
but given the immense amount of tricky involved with both PI and futex there is bound to be something I've overlooked.
Do people have more/better futex-pi test cases?
