From fd1b57ac73f169a5ba7a9569989aad40184f6340 Mon Sep 17 00:00:00 2001 From: Andy Whitcroft Date: Fri, 23 Mar 2012 15:02:18 -0700 Subject: checkpatch: high precedence operators do not require additional parentheses in #defines With any very high precedence operator it is not necessary to enforce additional parentheses around simple negated expressions. This prevents us requesting further perentheses around the following: #define PMEM_IS_FREE(id, index) !(pmem[id].bitmap[index].allocated) For now add logical and bitwise not and unary minus.
