Subject: [PATCH 8/8] blktrace: use helper in blk_trace_setup_lba()
Date: Thu, 13 Jun 2019 07:59:55 -0700	[thread overview]
Message-ID: <20190613145955.4813-9-chaitanya.kulkarni@wdc.com> (raw)
In-Reply-To: <20190613145955.4813-1-chaitanya.kulkarni@wdc.com>

This patch updates the blk_trace_setup_lba() with newly introduced helper
function to read the nr_sects from block device's hd_parts with the
help if part_nr_sects_read() protected by appropriate locking.
