Date: Thu, 9 Nov 2006 13:46:32 +0000 From: Russell King <rmk+lkml@....linux.org.uk> To: Linux Kernel List <linux-kernel@...r.kernel.org>, Linus Torvalds <torvalds@...l.org>, Andrew Morton <akpm@...l.org> Subject: [PATCH] Fix missing parens in set_personality() If you call set_personality() with an expression such as: set_personality(foo ? PERS_FOO1 : PERS_FOO2); then this evaluates to: ((current->personality == foo ? PERS_FOO1 : PERS_FOO2) ? ... which is obviously not the intended result. Add the missing parents to ensure this gets evaluated as expected: ((current->personality == (foo ? PERS_FOO1 : PERS_FOO2)) ? ...
