Its filename was mm-damon-core-validate-number-of-probes-in-valid_probe_params.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: SJ Park Subject: mm/damon/core: validate number of probes in valid_probe_params() Date: Tue, 1 Sep 2026 22:47:37 -0700 Each DAMON context is allowed to have only up to DAMON_MAX_PROBES probes. The central place for validating DAMON probe parameters, damon_valid_probe_params(), is not validating the upper limit, though. Do the validation.
