From 53c2bd679017277fce41101ae86ab51a234c29f7 Mon Sep 17 00:00:00 2001 From: наб Date: Fri, 16 Sep 2022 00:38:46 +0200 Subject: a.out: remove define-only CMAGIC, previously magic number MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The last user was removed in 5.1 in commit 08300f4402ab ("a.out: remove core dumping support") but this is part of the UAPI headers, so this may want to either wait until a.out is removed entirely, or be removed from the magic number doc and silently remain in the header A cursory glance on DCS didn't show any user code actually using this value Found with grep MAGIC Documentation/process/magic-number.rst | while read -r mag _; do git grep -wF "$mag" | grep -ve '^Documentation.*magic-number.rst:' \ -qe ':#define '"$mag" || git grep -wF "$mag" | while IFS=: read -r f _; do sed -i '/\b'"$mag"'\b/d' "$f"; done ; done Signed-off-by: Ahelenia Ziemiańska Link: https://lore.kernel.org/r/9cbea062df7125ef43e2e0b2a67ede6ad1c5f27e.1663280877.git.nabijaczleweli@nabijaczleweli.xyz Signed-off-by: Greg Kroah-Hartman --- include/uapi/linux/a.out.h | 3 --- 1 file changed, 3 deletions(-) (limited to 'include') diff --git a/include/uapi/linux/a.out.h b/include/uapi/linux/a.out.h index 5fafde3798e5..bb15da96df2a 100644 --- a/include/uapi/linux/a.out.h +++ b/include/uapi/linux/a.out.h @@ -70,9 +70,6 @@ enum machine_type { The first page is unmapped to help trap NULL pointer references */ #define QMAGIC 0314 -/* Code indicating core file. */ -#define CMAGIC 0421 - #if !defined (N_BADMAG) #define N_BADMAG(x) (N_MAGIC(x) != OMAGIC \ && N_MAGIC(x) != NMAGIC \ -- cgit v1.2.3-59-g8ed1b
