Date: Wed, 20 Feb 2019 19:33:41 -0800 From: Randy Dunlap <rdunlap@...radead.org> To: LKML <linux-kernel@...r.kernel.org>, Andrew Morton <akpm@...ux-foundation.org> Cc: Matthew Wilcox <willy@...radead.org> Subject: [PATCH] <linux/kernel.h>: drop the gcc-3.3 'const' hack in roundup() From: Randy Dunlap <rdunlap@...radead.org> The single quotation marks around "const" were causing a documentation markup warning with reST. Instead of fixing that warning, just delete that comment line and the gcc-3.3 hack of using "const" in the roundup() macro since gcc-3.3 is no longer supported for kernel builds. I did around 20 different $arch builds with no problems, but we'll just have to see if this causes problems for anyone else out there.
