[PATCH 0/5] Followup folio conversions for zswap

From: Matthew Wilcox (Oracle)
Date: Sat Jul 15 2023 - 00:24:13 EST


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.

Matthew Wilcox (Oracle) (5):
fix-frontswap
zswap: Make zswap_store() take a folio
memcg: Convert get_obj_cgroup_from_page to get_obj_cgroup_from_folio
swap: Remove some calls to compound_head() in swap_readpage()
zswap: Make zswap_load() take a folio
