Its filename is arc-use-generic-dump_stack_print_cmdline-implementation.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/arc-use-generic-dump_stack_print_cmdline-implementation.patch This patch will later appear in the mm-nonmm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Helge Deller Subject: arc: use generic dump_stack_print_cmdline() implementation Date: Mon, 8 Aug 2022 15:09:17 +0200 The process program name and command line is now shown in generic code in dump_stack_print_info(), so drop the arc-specific implementation.
