kernel: futex: Drop CLONE_THREAD requirement for private default hash alloc

A flaw was found in the Linux kernel's futex subsystem. The needfutexhashallocatedefault function incorrectly relies on CLONETHREAD semantics, which can lead to non-concurrency issues when memory allocations mm-futexref pcpu allocations are shared across CLONEVM clones, excluding vfork. This can...
