From 6dac02a5e1bba0bb88ece50160fc4a64cccf30d1 Mon Sep 17 00:00:00 2001 From: "Artem B. Bityutskiy" Date: Mon, 18 Jul 2005 12:21:23 +0100 Subject: [PATCH] [JFFS2] Fix slab panic When JFFS22 is unable to read the root inode, the bad root inode object is not freed and remains sticked in the jffs2_i slab cache. When we further try to free the slab cache (e.g., on rmmod jffs2), slab allocator subsystem panics. Fix this bug. Signed-off-by: Artem B.
