[CRIU] [PATCH 0/1] do_new_mount() should clear all do_change_type() bits

[Oleg Nesterov]

So I hit the new problems with criu. I'll write another email,
I beleive the recent --ext-mount-map auto were not 100% correct.

But don't we need this change in any case? So far I do not know
how to test it, but it seems that do_new_mount()->mount() will
obviously fail if MS_SLAVE is set?

Please review, so far only compile tested.

Oleg.
