In order to prevent request_queue to be freed before cleaning up
blktrace debugfs entries, commit db59133e9279 ("scsi: sg: fix blktrace
debugfs entries leakage") use scsi_device_get(), however,
scsi_device_get() will also grab scsi module reference and scsi module
can't be removed.

I just noticed that this patch has been posted on the linux-scsi mailing list. If you plan to resend this patch, please send it to Jens and Cc both linux-block and linux-scsi because this patch fixes a bug in a patch that only exists in Jens' tree.

Thanks,

Bart.
