From 45aa6a1a2cca3847caed029e2b788fb4ae41c93c Mon Sep 17 00:00:00 2001 From: Suganath Prabu Subramani Date: Tue, 31 Oct 2017 18:02:36 +0530 Subject: [PATCH] scsi: mpt3sas: NVMe drive support for BTDHMAPPING ioctl command and log info * Added debug prints for pcie devices in ioctl debug path. Which will be helpful for debugging. * Added PCIe device support for ioctl BTDHMAPPING ioctl. Signed-off-by: Chaitra P B Signed-off-by: Suganath Prabu S Signed-off-by: Martin K.
