Hi sorry for the delay.
So the patch works for the kernel panic.
Reported-and-Tested-by: Tao Ma
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:
[] ? kmem_cache_destroy+0x83/0xc7
[] ? destroy_inodecache+0x15/0x17 [ext4]
[] ? ext4_exit_fs+0x30/0x60 [ext4]
[] ? sys_delete_module+0x1b5/0x218
[] ? audit_syscall_entry+0x187/0x1ba
[] ? 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.
