The quilt patch titled Subject: powerpc: assert_pte_locked() use pte_offset_map_ro_nolock() has been removed from the -mm tree. Its filename was powerpc-assert_pte_locked-use-pte_offset_map_ro_nolock.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: Qi Zheng <zhengqi.arch@xxxxxxxxxxxxx> Subject: powerpc: assert_pte_locked() use pte_offset_map_ro_nolock() Date: Thu, 26 Sep 2024 14:46:15 +0800 In assert_pte_locked(), we just get the ptl and assert if it was already held, so convert it to using pte_offset_map_ro_nolock().
