commit35a635af54upstream. In lpfc_release_io_buf, an lpfc_io_buf is returned to the 'available' pool before any associated sgl or cmd and rsp buffers are returned via their respective 'put' routines. If xri rebalancing occurs and an lpfc_io_buf structure is reused quickly, there may be a race condition between release of old and association of new resources. Re-ordered lpfc_release_io_buf to release sgl and cmd/rsp buffer lists before releasing the lpfc_io_buf structure for re-use. Fixes:d79c9e9d4b("scsi: lpfc: Support dynamic unbounded SGL lists on G7 hardware.")

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.
