From 9e46d7c03b82e2158ccac12be841002a0ba92bab Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 12 Jul 2021 17:24:30 +0100 Subject: [PATCH] gfs2: Fix memory leak of object lsi on error return path [ Upstream commit a6579cbfd7216b071008db13360c322a6b21400b ] In the case where IS_ERR(lsi->si_sc_inode) is true the error exit path to free_local does not kfree the allocated object lsi leading to a memory leak. Fix this by kfree'ing lst before taking the error exit path.
