Subject: [PATCH 0/1] exec: do not sleep in TASK_TRACED under
	->cred_guard_mutex

I cc'ed Linus and stable, but I don't know how to really test this patch
and I don't really understand the new creds management.

Please review.

load_flat_shared_library() does something strange (but hopefully this
patch doesn't break it). I do not understand why does it create the
new bprm. Afaics, it could reuse bprm pointer which comes as an argument
of ->load_binary(), all we need is to temporary change/restore bprm->file
for load_flat_file().

Oleg.
