Hi sorry for the delay.
So the patch works for the kernel panic.
Reported-and-Tested-by: Tao Ma <boyu.mt@...bao.com>

As for the original bug, it doesn't help. I can still get the error message.

slab error in kmem_cache_destroy(): cache `ext4_inode_cache': Can't free all
objects
Pid: 4674, comm: rmmod Not tainted 2.6.38-rc2+ #1
Call Trace:

 [<ffffffff82002a6b>] ? system_call_fastpath+0x16/0x1b
SLAB: cache with size 888 has lost its name

And as I pointed in the original mail, I have done some basic investigation and
it looks as if it is introduced by Nick's new ext4_i_callback.
