Subject: [PATCH v2 0/4] futex: Fixups for the testsuite and FUTEX_NUMA

This is a collection of random fixes related to the recent private
futex/ NUMA addition:

 - Some of the test fail on ARM due bad command line parsing.

 - The MPOL test fails because the home node was never set.

 - The syzbot used a negative NODE number which was not tested for.

v1…v2: https://lore.kernel.org/all/20250528085521.1938355-1-bigeasy@linutronix.de/
  - Extend 4/4 to also check for the immutable flag.

Peter Zijlstra (1):
  futex: Handle invalid node numbers supplied by user

Sebastian Andrzej Siewior (3):
  selftests/futex: getopt() requires int as return value.
  selftests/futex: Set the home_node in futex_numa_mpol
  futex: Verify under the lock if hash can be replaced
