Subject: [PATCH v2 0/6] uprobes: fix fork() with the pending ret-probe(s)

Hello.

This series fixes the serious bug reported by Martin and David
and cc's stable. See the changelog in 5/6.

The changes are minimal, I am sending v2 just in case before I
ask to pull.

v2:

	2/6: whitespace fix

	4/6: update the changelog to explain why we do not cleanup
	     the child's stack instead

	5/6: check area != NULL before dup xol_area

	1-5: add the acks from Srikar. I assume he agrees with 6/6
	     as well.


Oleg.
