[PATCH 0/4] mm/mempolicy: kernel_migrate_pages: fix race between security checks and suid exec

[Oleg Nesterov]

Hello,

Sorry, I have no idea how to test these changes. Please review.
Hopefully sashiko.dev will take a look too ;)

find_mm_struct() has the same problem, will send a patch tomorrow.
Unless you tell me this race doesn't need a fix.

Oleg.
