Subject: [PATCH v3 0/6] tlb: Fix (soft-)dirty bit management & clean up API
Date: Wed, 27 Jan 2021 23:53:41 +0000	[thread overview]
Message-ID: <20210127235347.1402-1-will@kernel.org> (raw)

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.

Will
