From a90e8b6fb80db43b029e1e76205452afa8bdc77a Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Tue, 8 Nov 2011 16:47:55 +0200 Subject: [PATCH] Btrfs: fix memory leak in btrfs_parse_early_options() Don't leak subvol_name string in case multiple subvol= options are given. "The lastest option is effective" behavior (consistent with subvolid= and subvolrootid= options) is preserved.
