Subject: [PATCH 04/17] nvme: lightnvm: make MLC num_pairs little endian
Date: Thu, 7 Jul 2016 09:54:10 +0200 [thread overview]
Message-ID: <1467878063-22919-5-git-send-email-m@bjorling.me> (raw)
In-Reply-To: <1467878063-22919-1-git-send-email-m@bjorling.me>
From: Johannes Thumshirn <jthumshirn@suse.de>
According to the OpenChannel SSD interface specification the NAND flash
MLC page pairing information's number of page page pairings field is the
first two bytes in the MLC Page Pairing data structure. The hardware's
data structure itself is little endian so annotate it as such, like the
rest of lighnvm's data structures.
