From b7d8ac3e1779c30ddef0a8f38042076c5007a23d Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Thu, 19 Oct 2006 16:02:07 +0200 Subject: [PATCH] [GFS2] gfs2_dir_read_data(): fix uninitialized variable usage In the "if (extlen)" case, "bh" was used uninitialized. This patch changes the code to what seems to have been intended. Spotted by the Coverity checker. This patch also removes a pointless "bh = NULL" asignment (the variable is never accessed again after this point).
