From 61ce339f19fabbc3e51237148a7ef6f2270e44fa Mon Sep 17 00:00:00 2001 From: Rishabh Bhatnagar Date: Tue, 20 Sep 2022 19:19:32 +0000 Subject: [PATCH] nvme-pci: set min_align_mask before calculating max_hw_sectors If swiotlb is force enabled dma_max_mapping_size ends up calling swiotlb_max_mapping_size which takes into account the min align mask for the device. Set the min align mask for nvme driver before calling dma_max_mapping_size while calculating max hw sectors.
