Merge tag 'selinux-pr-20231030' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux updates from Paul Moore:
- improve the SELinux debugging configuration controls in Kconfig
- print additional information about the hash table chain lengths when
when printing SELinux debugging information
- simplify the SELinux access vector hash table calcaulations
- use a better hashing function for the SELinux role tansition hash
table
- improve SELinux load policy time through the use of optimized
functions for calculating the number of bits set in a field
- addition of a __counted_by annotation
- simplify the avtab_inert_node() function through a simplified
prototype
