That's correct. Part of the flow control improvement was to get rid of needless

Callers of cmpxchg_futex_value_locked() can trigger the following:
kernel/futex.c: In function ‘futex_lock_pi_atomic’:

This was initially addressed by commit 7cfdaf38, but others still remain.
From: Davidlohr Bueso
Currently, the futex global hash table suffers from it's fixed, smallish
(for today's standards) size of 256 entries, as well as its lack of NUMA
awareness. Large systems, using many futexes, can be prone to high amounts
of collisions; where these futexes hash to the same bu

In futex_wake() there is clearly no point in taking the hb->lock if we know
beforehand that there are no tasks to be woken. While the hash bucket's plist

After some discussions of the patch last week, here is a new version.
Simply reducing the post_table did not work, as for some frequencies
both settings (MCLKDIV=0 and MCLKDIV=1) are needed (e.g. 96 and 192kHz)
