Subject: [PATCH 5.4 50/57] nvme: Cleanup and rename nvme_block_nr()
Date: Mon,  5 Oct 2020 17:27:02 +0200	[thread overview]
Message-ID: <20201005142112.202881686@linuxfoundation.org> (raw)
In-Reply-To: <20201005142109.796046410@linuxfoundation.org>

From: Damien Le Moal <damien.lemoal@wdc.com>

commit 314d48dd224897e35ddcaf5a1d7d133b5adddeb7 upstream.

Rename nvme_block_nr() to nvme_sect_to_lba() and use SECTOR_SHIFT
instead of its hard coded value 9. Also add a comment to decribe this
helper.
