The original code in commit24d2f90309("blk-mq: split out tag initialization, support shared tags") would check tags->rqs is non-NULL and then dereference tags->rqs[]. Then in commit2af8cbe305("blk-mq: split tag ->rqs[] into two"), we started to dereference tags->static_rqs[], but continued to check non-NULL tags->rqs. Check tags->static_rqs as non-NULL instead, which is more logical.

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.
