Subject: [PATCH 0/2] mm: devmap: page-freeing related cleanups
Date: Thu, 14 Nov 2019 16:11:32 -0800 [thread overview]
Message-ID: <20191115001134.2489505-1-jhubbard@nvidia.com> (raw)
Hi,
Here are the small devmap page-freeing cleanups as requested, so that
they can be reviewed separately from the larger "track dma-pinned pages
series" [1] that they were originally part of.
I did not add Jan Kara's and Jerome Glisse's reviewed-by tags, because those
were for patch 2 but as part of [1], which is different enough from this
series that I couldn't treat it as "close enough".
Testing: Dan notes that his patch (1) has passed nvdimm unit tests. However,
I have not yet done much testing of the two patches together. What
I've done so far is to boot up a system that has CONFIG_DEV_PAGEMAP_OPS=y
and run LTP tests on it, but none of those tests are exercising
free_devmap_managed_page().
Dan, if you could run this combined set through your unit tests, I'd feel
a lot better about it. I'll also work on getting my HMM test setup revived.
