Subject: blkid: use /dev/mapper/<name> rather than /dev/dm-<N>
X-Git-Tag: v1.41.6~32
X-Git-Url: http://git.kernel.org/?p=fs%2Fext2%2Fe2fsprogs.git;a=commitdiff_plain;h=4271e23942bdc60e1fa6c0b26bc666a94a8b3e1d

blkid: use /dev/mapper/<name> rather than /dev/dm-<N>

The libblkid (since v1.41.1) returns private device-mapper names (e.g.
/dev/dm-0). It's because the probe_one() function scans /dev before
/dev/mapper.

brw-rw---- 1 root disk 253, 0 2009-04-27 13:41 /dev/dm-0
brw-rw---- 1 root disk 253, 0 2009-04-27 13:41 /dev/mapper/TestVolGroup-TestLogVolume

Old version:
  # blkid -t LABEL="TEST-LABEL" -o device
  /dev/dm-0

Fixed version:
  # blkid -t LABEL="TEST-LABEL" -o device
  /dev/mapper/TestVolGroup-TestLogVolume
