Message

This series contains some boolean code simplifications that I discovered
while working on another patch. I believe they also save some run time
(although not in any perf-critical paths) and some memory overhead.

Changes in v2:
 - drop already merged 1st patch
 - drop the rewrite of security_preserve_bools(), keep only the
   evaluate_cond_node() return type change (requested by Paul)

Ondrej Mosnacek (5):
  selinux: simplify evaluate_cond_node()
  selinux: convert cond_list to array
  selinux: convert cond_av_list to array
  selinux: convert cond_expr to array
  selinux: generalize evaluate_cond_node()
