Subject: [PATCH 0/4] Use new infrastructure in more simple cases

This continues the execve anti-deadlock patch and addresses all
of the (mostly) simple cases, there the new exec_update_mutex
can be used instead of the cred_guard_mutex.

Note: each of these patches is independent of each other, so
in case one of them turns out to be controversial, that does
not affect the others.

Bernd Edlinger (4):
  kernel/kcmp.c: Use new infrastructure to fix deadlocks in execve
  proc: Use new infrastructure to fix deadlocks in execve
  proc: io_accounting: Use new infrastructure to fix deadlocks in execve
  perf: Use new infrastructure to fix deadlocks in execve
