The hv_compose_msi_msg() callback in irq_chip::irq_compose_msi_msg is invoked via irq_chip_compose_msi_msg(), which itself is always invoked from atomic contexts from the guts of the interrupt core code. There is no way to change this w/o rewriting the whole driver, so use tasklet_disable_in_atomic() which allows to make tasklet_disable() sleepable once the remaining atomic users are addressed.

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.
