From a52a4d7a57a4e83ed6cdc1b11bd5c8f1b5c8c86b Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Tue, 31 May 2011 08:40:40 +0300 Subject: [PATCH] UBIFS: fix memory leak on error path commit 812eb258311f89bcd664a34a620f249d54a2cd83 upstream. UBIFS leaks memory on error path in 'ubifs_jnl_update()' in case of write failure because it forgets to free the 'struct ubifs_dent_node *dent' object. Although the object is small, the alignment can make it large - e.g., 2KiB if the min. I/O unit is 2KiB.
