- Core locking & atomics:
- Convert all architectures to ARCH_ATOMIC: move every
architecture to ARCH_ATOMIC, then get rid of ARCH_ATOMIC
and all the transitory facilities and #ifdefs.
Much reduction in complexity from that series:
63 files changed, 756 insertions(+), 4094 deletions(-)
- Self-test enhancements
- Futexes:
- Add the new FUTEX_LOCK_PI2 ABI, which is a variant that
doesn't set FLAGS_CLOCKRT (.e. uses CLOCK_MONOTONIC).
[ The temptation to repurpose FUTEX_LOCK_PI's implicit
setting of FLAGS_CLOCKRT & invert the flag's meaning
to avoid having to introduce a new variant was
resisted successfully. ]
- Enhance futex self-tests
- Lockdep:
- Fix dependency path printouts
- Optimize trace saving
- Broaden & fix wait-context checks
- Misc cleanups and fixes.
