sg_ioctl() support to enable blktrace, which will create debugfs entries "/sys/kernel/debug/block/sgx/", however, there is no guarantee that user will remove these entries through ioctl, and deleting sg device doesn't cleanup these blktrace entries. This problem can be fixed by cleanup blktrace while releasing request_queue, however, it's not a good idea to do this special handling in common layer just for sg device. Fix this problem by shutdown bltkrace in sg_device_destroy(), where the device is deleted and all the users close the device, also grab a scsi_device reference from sg_add_device() to prevent scsi_device to be freed before sg_device_destroy(); Signed-off-by: Yu Kuai <yukuai3@huawei.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Martin K.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
