The patch titled Subject: mm/mglru: drop unused parameter has been added to the -mm mm-unstable branch. Its filename is mm-mglru-drop-unused-parameter.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-mglru-drop-unused-parameter.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: Kinsey Ho <kinseyho@xxxxxxxxxx> Subject: mm/mglru: drop unused parameter Date: Wed, 14 Feb 2024 06:05:34 +0000 Patch series "mm/mglru: code cleanup and refactoring" This provides MGLRU code cleanup and refactoring for better readability. This patch (of 5): struct scan_control *sc is currently passed into try_to_inc_max_seq() and run_aging(). This parameter is not used. Drop the unused parameter struct scan_control *sc. No functional change.
