The quilt patch titled Subject: ia64: ptrace: user_regset_copyin_ignore() always returns 0 has been removed from the -mm tree. Its filename was ia64-ptrace-user_regset_copyin_ignore-always-returns-0.patch This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Sergey Shtylyov <s.shtylyov@xxxxxx> Subject: ia64: ptrace: user_regset_copyin_ignore() always returns 0 Date: Sat, 15 Oct 2022 00:22:27 +0300 user_regset_copyin_ignore() always returns 0, so checking its result seems pointless -- don't do this anymore...
