Hello, I found a bug in the rtl8192u module. When removing the module, I got the following warning: [ 20.407360] remove_proc_entry: removing non-empty directory 'net/rtl819xU', leaking at least 'wlan0' [ 20.408609] WARNING: CPU: 4 PID: 451 at fs/proc/generic.c:718 remove_proc_entry+0x2e1/0x3e0 [ 20.412316] RIP: 0010:remove_proc_entry+0x2e1/0x3e0 [ 20.420050] Call Trace: [ 20.421178] rtl8192_usb_module_exit+0x4a/0x63 [r8192u_usb] I think the problem is the misuse of the proc entry, but I'm not familiar with the driver, so I'm reporting the bug to you. regards, Zheyu Ma
