[0/6] exec: Trivial cleanups for exec

Message

This is a continuation of my work to clean up exec so it's more
difficult problems are approachable.

The changes correct some comments, stop open coding mutex_lock_killable,
and move the point_of_no_return variable up to when the
point_of_no_return actually occurs.

I don't think there is anything controversial in there but if you see
something please let me know.

Eric W. Biederman (6):
      exec: Move the comment from above de_thread to above unshare_sighand
      exec: Fix spelling of search_binary_handler in a comment
      exec: Stop open coding mutex_lock_killable of cred_guard_mutex
      exec: Run sync_mm_rss before taking exec_update_mutex
      exec: Move handling of the point of no return to the top level
      exec: Set the point of no return sooner
