[PATCH 0/6] make request_module() killable

[Oleg Nesterov]

As Tetsuo pointed out, request_module() is very much unfriendly wrt OOM.
It needs "a lot" of time/memory to finish while the caller is blocked in
TASK_UNINTERRUPTIBLE.

Changes:

	- improve the comments a bit

	- reorder the changes so that 3/6 which changes kABI can be
	  skipped, to simplify the backporting

	- tried to test, seems to work

This series is orthogonal to kmod-avoid-deadlock-by-recursive-kmod-call.patch
(which I still think should be replaced, I'll try to return to this later).

3/6 depends on usermodehelper-use-umh_wait_proc-consistently.patch


Many thanks to Tetsuo for the discussion.

Oleg.
