Subject: [PATCH v3 0/5] Increase mseal test coverage

From: Jeff Xu <jeffxu@...omium.org>

This series increase the test coverage of mseal_test by:

Add check for vma_size, prot, and error code for existing tests.
Add more testcases for madvise, munmap, mmap and mremap to cover
sealing in different scenarios.

The increase test coverage hopefully help to prevent future regression.
It doesn't change any existing mm api's semantics, i.e. it will pass on
linux main and 6.10 branch.

Note: in order to pass this test in mm-unstable, mm-unstable must have
Liam's fix on mmap [1]
