In host reset, we use TMF or soft-reset to re-init device, and if success, we will release all LLDD resources of this device. If the init fails - maybe because the device was removed or link has not come up - then do not release the LLDD resources, but rather rely on SCSI EH to handle the timeout for these resources later on. But if clear nexus ha calls host reset, which is the last effort of SCSI EH, we should release all LLDD remain resources. Because SCSI EH will release all tasks after clear nexus ha. Before release, we do I_T nexus reset to try to clear target remain IOs. Signed-off-by: Xiaofei Tan <tanxiaofei@huawei.com> Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
