Its filename was mm-damon-remove-__read_mostly-from-memory_idle_ms_percentiles.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: Li RongQing Subject: mm/damon/stat: remove __read_mostly from memory_idle_ms_percentiles Date: Fri, 30 Jan 2026 03:56:03 -0500 The 'memory_idle_ms_percentiles' array in DAMON_STAT is updated frequently by the kernel to reflect the latest idle time statistics. Marking it as '__read_mostly' is inappropriate for data that is regularly written to, as it can lead to cache pollution in the read-mostly section. Remove the '__read_mostly' annotation to accurately reflect the variable's usage pattern.
