zswap: make zswap_store() take a folio
Patch series "Followup folio conversions for zswap".
With frontswap killed, it's worth converting the zswap_load() and
zswap_store() functions to take a folio instead of a page pointer. They
aren't converted to support large folios, but there are a lot of
unnecessary calls to compound_head() that are removed by these patches.
This patch (of 4):
Only convert a few easy parts of this function to use the folio passed in;
convert back to struct page for the majority of it. This does remove a
few hidden calls to compound_head().
