From c56ee92fcba8cc922b1b2188ac20614d20223db2 Mon Sep 17 00:00:00 2001 From: Roman Kagan Date: Fri, 29 May 2020 01:55:10 +0300 Subject: block: consolidate blocksize properties consistency checks Several block device properties related to blocksize configuration must be in certain relationship WRT each other: physical block must be no smaller than logical block; min_io_size, opt_io_size, and discard_granularity must be a multiple of a logical block. To ensure these requirements are met, add corresponding consistency checks to blkconf_blocksizes, adjusting its signature to communicate possible error to the caller. Also remove the now redundant consistency checks from the specific devices.
