From 0eb28a42284ec32e6f283985d2d638474a05eba4 Mon Sep 17 00:00:00 2001 From: Ekaterina Tumanova Date: Mon, 16 Feb 2015 12:47:58 +0100 Subject: BlockConf: Call backend functions to detect geometry and blocksizes geometry: hd_geometry_guess function autodetects the drive geometry. This patch adds a block backend call, that probes the backing device geometry. If the inner driver method is implemented and succeeds (currently only for DASDs), the blkconf_geometry will pass-through the backing device geometry. Otherwise will fallback to old logic. blocksize: This patch initializes blocksize properties to 0. In order to set the property a blkconf_blocksizes was introduced. If user didn't set physical or logical blocksize, it will retrieve its value from a driver (only succeeds for DASD), otherwise it will set default 512 value. The blkconf_blocksizes call was added to all users of BlkConf.
