#     Merge branch 'exec-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull execve updates from Eric Biederman:
#      "Last cycle for the Nth time I ran into bugs and quality of
#       implementation issues related to exec that could not be easily be
#       fixed because of the way exec is implemented. So I have been digging
#       into exec and cleanup up what I can.
#     
#       I don't think I have exec sorted out enough to fix the issues I
#       started with but I have made some headway this cycle with 4 sets of
#       changes.
#     
#        - promised cleanups after introducing exec_update_mutex
#     
#        - trivial cleanups for exec
#     
#        - control flow simplifications
#     
#        - remove the recomputation of bprm->cred
#     
#       The net result is code that is a bit easier to understand and work
#       with and a decrease in the number of lines of code (if you don't count
#       the added tests)"
#
