From 1fdd366b9de1a1ae1532b1b9bff92124aef04721 Mon Sep 17 00:00:00 2001 From: Oskar Schirmer Date: Wed, 10 Nov 2010 21:06:13 +0000 Subject: [PATCH] cifs: fix another memleak, in cifs_root_iget commit a7851ce73b9fdef53f251420e6883cf4f3766534 upstream. cifs_root_iget allocates full_path through cifs_build_path_to_root, but fails to kfree it upon cifs_get_inode_info* failure. Make all failure exit paths traverse clean up handling at the end of the function.
