The patch titled Subject: mm/swap: remove the end_write_func argument to __swap_writepage has been added to the -mm mm-unstable branch. Its filename is mm-remove-the-end_write_func-argument-to-__swap_writepage.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-remove-the-end_write_func-argument-to-__swap_writepage.patch This patch will later appear in the mm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Christoph Hellwig <hch@xxxxxx> Subject: mm/swap: remove the end_write_func argument to __swap_writepage Date: Thu, 11 Aug 2022 16:17:41 +0200 The argument is always set to end_swap_bio_write, so remove the argument and mark end_swap_bio_write static.
