Yes, please drop the patch #4 since it requires different solution, I
do not think it's critical enough to have partial solution and it has
been that way for a long time. We can fix it later.

Ok, I'll run some tests and resend it right away without the patch

Thanks!  So should I drop patch #4 for now?  I don't think it does any
harm, and it does plug the hole somewhat, but Cristoph is right that
we still could have swapon racing with the fallocate.
