Well gee. Given a choice, I went and replied to the wrong thread.
Here's what I think:
From: Andrew Morton <akpm@linux-foundation.org>
Herton Krzesinski reports that the error-checking changes in
04ebd4aee52b06a2c38127d9208546e5b96f3a19 ("block/ioctl.c and
fs/partition/check.c: check value returned by add_partition") cause his
buggy USB camera to no longer mount. "The camera is an Olympus X-840.
The original issue comes from the camera itself: its format program
creates a partition with an off by one error".
Buggy devices happen. It is better for the kernel to warn and to proceed
with the mount.
