* lib/sysfs: fix sysfs_devname_to_devno for dm partitionsPeter Rajnoha2012-09-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Partitions mapped by device-mapper are not like real partitions where there's a /sys/block/<parent>/<name>/dev sysfs path. We need to look at /sys/block/<name>/dev like we do for any other non-partition devices. The mapped partition is not found otherwise. For example, this bug shows up in lsblk while specifying a device on command line while that device is a dm mapping over a partition: $lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 128M 0 disk `-test (dm-0) 253:0 0 128M 0 dm `-test1 (dm-1) 253:1 0 127M 0 part Before this patch: $lsblk /dev/mapper/test1 lsblk: dm-1: unknown device name With this patch: $lsblk /dev/mapper/test1 NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT test1 (dm-1) 253:1 0 127M 0 part

* lib: do not attempt to close(0) in sysfs_deinit()Petr Uzel2011-09-131-0/+1
| | | | | | | | | | | If the 'open' fails we 'goto err' which runs 'sysfs_deinit()' on a 'cxt' which hasn't been fully initialised. The 'dir_fd' is still 0, so sysfs_deinit calls "close(0)".
