Merge tag 'audit-pr-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit
Pull audit updates from Paul Moore:
"Another small pull request for audit, most of the patches are
documentation updates with only two real code changes: one to fix a
compiler warning for a dummy function/macro, and one to cleanup some
code since we removed the AUDIT_FILTER_ENTRY ages ago (v4.17)"
* tag 'audit-pr-20210426' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit:
audit: drop /proc/PID/loginuid documentation Format field
audit: avoid -Wempty-body warning
audit: document /proc/PID/sessionid
audit: document /proc/PID/loginuid
MAINTAINERS: update audit files
