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. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
