+Subject: [PATCH 143/323] PCI: hv: Use tasklet_disable_in_atomic()
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10.204-rt100.tar.xz
+
+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.
