Date: Sun, 20 Dec 2020 21:36:32 +0100 Message-Id: <20201220203638.43615-1-bigeasy@linutronix.de> MIME-Version: 1.0 Precedence: bulk List-ID: X-Mailing-List: linux-scsi@vger.kernel.org Folks, in the discussion about preempt count consistency across kernel configurations: https://lore.kernel.org/r/20200914204209.256266093@linutronix.de/ it was concluded that the usage of in_interrupt() and related context checks should be removed from non-core code. In the long run, usage of 'preemptible, in_*irq etc.' should be banned from driver code completely. This series addresses the target subsystem. Most of in_interrupt() usage is debugging. There is one function which either invokes wait_for_completion() or schedules a timer based on in_interrupt(). Sebastian
