Subject: [PATCH V1 01/13] iommu/hyperv: rename hyperv-iommu.c to hyperv-irq.c
Date: Tue, 21 Apr 2026 19:32:27 -0700 [thread overview]
Message-ID: <20260422023239.1171963-2-mrathor@linux.microsoft.com> (raw)
In-Reply-To: <20260422023239.1171963-1-mrathor@linux.microsoft.com>
This file actually implements irq remapping, so rename to more appropriate
hyperv-irq.c. A new file to implement hyperv iommu will be introduced
later. Also, it should not be tied to HYPERV_IOMMU, but to CONFIG_HYPERV
and IRQ_REMAP. The file already has #ifdef CONFIG_IRQ_REMAP.
Signed-off-by: Mukesh R <mrathor@linux.microsoft.com>
