Its filename was mm-vmalloc-initialize-vas-list-node-after-unlink.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: "Uladzislau Rezki (Sony)" Subject: mm/vmalloc: initialize VA's list node after unlink Date: Tue, 7 Jun 2022 11:34:47 +0200 A vmap_area can travel between different places. For example attached/detached to/from different rb-trees. In order to prevent fancy bugs, initialize a VA's list node after it is removed from the list, so it pairs with VA's rb_node which is also initialized. There is no functional change as a result of this patch.
