Subject: io_uring: stop calling free_compound_page()
Date: Wed, 16 Aug 2023 16:11:49 +0100

Patch series "Remove _folio_dtor and _folio_order", v2.


This patch (of 13):

folio_put() is the standard way to write this, and it's not appreciably
slower.  This is an enabling patch for removing free_compound_page()
entirely.
