This series fixes several correctness issues in mremap_test and
simplifies and strengthens its data validation.
Patch 1 converts the mremap_test to use kselftest helpers, removes
manual tracking of failed tests and corrects some spelling errors.
Patches 2 to 5 fix userfaultfd skipping, unexpected mremap success
handling, multi-VMA data validation and failure reporting when data
corruption is detected.
Patch 6 removes the randomization and uses a simple pattern based approach.
Patch 7 removes perf tests and timing infrastructure.
Patch 8 removes validation threshold and always validates complete mappings.
Patch 9 strengthens the multi VMA validation by also checking the
mapping state of holes after remapping.
