From 7eaae2828dadae3abde7f77734c874d4b74b313a Mon Sep 17 00:00:00 2001 From: "KAMBAROV, ZAUR" Date: Thu, 7 Jul 2005 17:57:06 -0700 Subject: [PATCH] [PATCH] coverity: fs/locks.c flp null check We're dereferencing `flp' and then we're testing it for NULLness. Either the compiler accidentally saved us or the existing null-pointer checdk is redundant. This defect was found automatically by Coverity Prevent, a static analysis tool.
