Subject: [PATCH] headers: linux/mutex.h: drop linkage.h
Date: Sat, 24 Feb 2018 21:22:12 -0800 [thread overview]
Message-ID: <582b3892-4e4c-06b2-a368-5c2d439de7fc@infradead.org> (raw)
From: Randy Dunlap <rdunlap@infradead.org>
<linux/mutex.h> does not use nor need <linux/linkage.h>, so drop that
one header file from mutex.h.
<linux/mutex.h> is currently #included in around 1250 C source files
(oops, I didn't count other header files that #include it), making it
the 27th most-used header file.
Build tested on i386 and x86_64 * (allnoconfig, tiny.config, defconfig,
allyesconfig, and allmodconfig) and x64_64 allmodconfig + SMP=disabled.
Signed-off-by: Randy Dunlap <rdunlap@infradead.org>
