[dm-devel] [PATCH 14/16] f2fs: call bdev_zone_sectors() only once on init_blkz_info()

[Pankaj Raghav]

From: Luis Chamberlain <mcgrof at kernel.org>

Instead of calling bdev_zone_sectors() multiple times, call
it once and cache the value locally. This will make the
subsequent change easier to read.
