Its filename was mm-change-to-return-bool-for-pmdp_clear_flush_young.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 pmdp_clear_flush_young() Date: Sat, 21 Mar 2026 14:42:52 +0800 The pmdp_clear_flush_young() is used to clear the young flag and flush the TLB, returning whether the young flag was set for this PMD entry. Change the return type to bool to make the intention clearer.
