From mboxrd@z Thu Jan 1 00:00:00 1970 From: keith.busch@intel.com (Keith Busch) Date: Tue, 29 Aug 2017 17:46:04 -0400 Subject: [PATCHv2 4/4] nvme: Use metadata for passthrough commands In-Reply-To: <1504043164-5398-1-git-send-email-keith.busch@intel.com> References: <1504043164-5398-1-git-send-email-keith.busch@intel.com> Message-ID: <1504043164-5398-5-git-send-email-keith.busch@intel.com> The ioctls' struct allows the user to provide a metadata address and length for a passthrough command. This patch uses these values that were previously ignored and deletes the now unused wrapper function.
