mm: return the folio from __read_swap_cache_async()
Patch series "More swap folio conversions".
These all seem like fairly straightforward conversions to me. A lot of
compound_head() calls get removed. And page_swap_info(), which is nice.
This patch (of 13):
Move the folio->page conversion into the callers that actually want that.
Most of the callers are happier with the folio anyway. If the
page_allocated boolean is set, the folio allocated is of order-0, so it is
safe to pass the page directly to swap_readpage().
