Signed-off-by: Laura Abbott <[email protected]> --- Came out of https://bugzilla.redhat.com/show_bug.cgi?id=1301295, I never heard back from the reporter so I've had this sitting around for a bit and haven't been able to confirm it fixes the crash. The logic makes sense for the crash though. --- fs/udf/partition.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/udf/partition.c b/fs/udf/partition.c index 5f861ed2..a8ee7fc 100644 --- a/fs/udf/partition.c +++ b/fs/udf/partition.c @@ -329,7 +329,7 @@ uint32_t udf_get_pblock_meta25(struct super_block *sb, uint32_t block, } inode = mdata->s_mirror_fe; - if (!inode) + if (IS_ERR(inode)) return 0xFFFFFFFF; retblk = udf_try_read_meta(inode, block, partition, offset); } -- 2.5.5
