Its filename was mm-damon-rename-config_damon_dbgfs-to-damon_dbgfs_deprecated.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: SeongJae Park Subject: mm/damon: rename CONFIG_DAMON_DBGFS to DAMON_DBGFS_DEPRECATED Date: Mon, 29 Jan 2024 17:35:41 -0800 DAMON debugfs interface is deprecated. The fact has documented by commit 5445fcbc4cda ("Docs/admin-guide/mm/damon/usage: add DAMON debugfs interface deprecation notice"). Commit 620932cd2852 ("mm/damon/dbgfs: print DAMON debugfs interface deprecation message") further started printing a warning message when users still use it. Many people don't read documentation or kernel log, though. Make the deprecation harder to be ignored using the approach of commit eb07c4f39c3e ("mm/slab: rename CONFIG_SLAB to CONFIG_SLAB_DEPRECATED"). 'make oldconfig' with 'CONFIG_DAMON_DBGFS=y' will get a new prompt with the explicit deprecation notice on the name. 'make olddefconfig' with 'CONFIG_DAMON_DBGFS=y' will result in not building DAMON debugfs interface. If there is a real user of DAMON debugfs interface, they will complain the change to the builder.
