From 766c5a3ecb319cff62612568d05756c85a759998 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=D0=BD=D0=B0=D0=B1?= Date: Fri, 16 Sep 2022 00:38:33 +0200 Subject: Documentation: remove nonexistent magic numbers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The entire file blames back to the start of git (minus whitespace from the RST translation and a typo fix): * there are changelog comments for March 1994 through to Linux 2.5.74 * struct tty_ldisc is two pointers nowadays, so naturally no magic * GDA_MAGIC is defined but unused, and it's been this way since start-of-git * M3_CARD_MAGIC isn't defined, because commit d56b9b9c464a ("[PATCH] The scheduled removal of some OSS drivers") removed the entire driver in 2006 * CS_CARD_MAGIC likewise since commit b5d425c97f7d ("more scheduled OSS driver removal") in 2007 * KMALLOC_MAGIC and VMALLOC_MAGIC were removed in commit e38e0cfa48ac ("[ALSA] Remove kmalloc wrappers"), six months after start of git * SLAB_C_MAGIC has never even appeared in git (removed in 2.4.0-test3pre6) magic-number.rst is a low-value historial relic at best and misleading cruft at worst, so start with cleaning out ones that only appear therein Automated: grep MAGIC Documentation/process/magic-number.rst | while read -r mag _; do git grep -wF "$mag" | grep -vq '^Documentation.*magic-number.rst:' || sed -i "/^$mag/d"
