Subject: [RFC][PATCH 00/12] mm: tweak page cache migration
Date: Tue, 06 Oct 2020 13:51:03 -0700 [thread overview]
Message-ID: <20201006205103.268F74A9@viggo.jf.intel.com> (raw)
First of all, I think this little slice of code is a bit
under-documented. Perhaps this will help clarify things.
I'm pretty confident the page_count() check in the first
patch is right, which is why I removed it outright. The
xas_load() check is a bit murkier, so I just left a
warning in for it.
