Summary: Iterating over VM_MIN_ADDRESS->VM_MAXUSER_ADDRESS can take a very long time iterating one page at a time (2**(log_2(SIZE)-12) operations), yielding possibly several days or even weeks on 64-bit Book-E, even for a largely empty, which can happen when swapping out a process by vmdaemon. Speed this up by instead finding the next PTE at or equal to the given VA. Reviewed by: bdragon Differential Revision: https://reviews.freebsd.org/D24238 |
