Its filename was mm-page_io-convert-write-completion-handlers-to-folios.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Tal Zussman Subject: mm/page_io: convert write completion handlers to folios Date: Sat, 29 Aug 2026 15:09:00 -0400 Patch series "mm/page_io: folio conversion cleanups", v2. Convert the remaining struct page usage in mm/page_io.c to folios. This removes one of the last callers of end_page_writeback(), along with the last caller of ClearPageReclaim(). This allows us to remove the PG_reclaim page accessors entirely. Clean up a few other stale references to pages throughout while at it. The rename of mm/page_io.c to mm/swap_io.c is deferred to a separate series. This patch (of 6): Convert swap_write_end() and swap_fs_write_complete() to operate on folios directly instead of going through the folio-compat page APIs. This removes calls to end_page_writeback() and set_page_dirty(), and the last caller of ClearPageReclaim(), saving two calls to compound_head() per folio on the write error path.
