During reclaim, we may release the txq->lock spinlock in order to call iwl_trans_tx to queue new frames. The iwl_trans_tx function expects to be called with BHs disabled and iwl_pcie_reclaim is most of the times called with BHs disabled already. However, reclaim can also happen after flushing a STA and in that case BHs will not be disabled. Solve this corner case by only releasing the spinlock but keeping BHs disabled.

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 reStructuredText 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.
