In linux kernel since version 4.14.326 (release Date: 2023-09-23)
This option sets the number of buckets used in the sidtab hashtable
to 2^SECURITY_SELINUX_SIDTAB_HASH_BITS buckets. The number of hash
collisions may be viewed at /sys/fs/selinux/ss/sidtab_hash_stats. If
chain lengths are high (e.g. > 20) then selecting a higher value here
will ensure that lookups times are short and stable.
