Subject[PATCH v3 0/6] tlb: Fix (soft-)dirty bit management & clean up API
Date
Hi everyone,

This is version three of the patches I previously posted here:

v1: https://lore.kernel.org/r/20201120143557.6715-1-will@kernel.org
v2: https://lore.kernel.org/r/20201210121110.10094-1-will@kernel.org

The objective is to fix the lacklustre TLB invalidation on the clear_refs
path and then augment the mmu_gather API to make it more difficult to
abuse.

Although there are other patch series pending to address related issues, I
don't think this relatively straightforward set of fixes should be blocked
on them.
