perf: Disable monitoring on setuid processes for regular users
There was a a bug in setup_new_exec(), whereby the test to disabled perf monitoring was not correct because the new credentials for the process were not yet committed and therefore the get_dumpable() test was never firing. The patch fixes the problem by moving the perf_event test until after the credentials are committed. Signed-off-by:Stephane Eranian <eranian@google.com> Tested-by:
