Its filename was mm-change-to-return-bool-for-ptep_clear_flush_young-clear_flush_young_ptes.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: Baolin Wang Subject: mm: change to return bool for ptep_clear_flush_young()/clear_flush_young_ptes() Date: Sat, 21 Mar 2026 14:42:50 +0800 The ptep_clear_flush_young() and clear_flush_young_ptes() are used to clear the young flag and flush the TLB, returning whether the young flag was set. Change the return type to bool to make the intention clearer.
