Re: [PATCH v5 6/7] mm/maps: read proc/pid/maps under per-vma lock

[Lorenzo Stoakes]

This patch results in some spam :) there's a stray mmap_assert_locked() in
anon_vma_name() that triggers constantly.

Andrew - I attach a fix-patch for this, could you apply as at least a temporary
fix? As mm-new is broken at the moment with this patch.

Suren - could you check and obviously suggest something more sensible if you
feel this isn't right.

I'm not actually sure if we'd always have the VMA read lock here, maybe we need
an 'assert mmap lock or vma lock' predicate?

Worth auditing other mmap lock asserts that might have been missed with this
change also.

Cheers, Lorenzo
