* libblkid: don't use CDROM_GET_CAPABILITY ioctl for DM devicesKarel Zak2017-07-121-1/+1
| | | | | | | | | For some reason kernel commit e980f62353c697cbf0c4325e43df6e44399aeb64 add extra warning when the ioctl is used for DM devices. It seems we can avoid this ioctl when the device has dm/uuid. Addresses: https://bugzilla.redhat.com/show_bug.cgi?id=1469532 Signed-off-by: Karel Zak <kzak@redhat.com>

* lib/sysfs: rename devname functions, cleanupKarel Zak2015-05-281-8/+5Star
| | | | | | | | | | | | | | | | | | Well, I don't have mental power to use function names like sysfs_devname_to_dev_name() so this patch renames to sysfs_devname_sys_to_dev() sysfs_devname_dev_to_sys() It also cleanups usage of the functions. We have to be sure that sysfs.c code returns regular devnames. The existence of the sysfs devnames (with '!') should be completely hidden in sysfs specific code.

* lib/sysfs: Fix /dev to /sys node name translationStanislav Brabec2015-05-281-1/+19
| | | | | | | | | | | | | | | d0dc6c1 introduced translation of /sys names to /dev names, as required by the kernel linux/drivers/base/core.c: device_get_devnode(). But there are other places of code that use /dev names in /sys. They need reverse translation from '/' to '!'. For example, fdisk -l returns empty list since a22c6eb for device nodes in subdirectories (used e. g. by cciss driver). Introduce yet another helper sysfs_dev_name_to_devname() and use it where appropriate. Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>
* Fix /sys to /dev node name translationStanislav Brabec2015-05-261-0/+18
| | | | | | | | | | | | | | linux/drivers/base/core.c: device_get_devnode() defines a translation of '!' in sysfs nodes to '/' in /dev nodes. The same translation has to be done to properly support device nodes with slash (e. g. device nodes of cciss driver and several other drivers). Introduce new helper sysfs_devname_to_devno() and use it where appropriate. Fixes for example lsblk -f on devices using cciss driver. Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>
