Subject: - small changes to name2dev:
X-Git-Tag: v1_7_100~5744
X-Git-Url: https://git.whamcloud.com/?a=commitdiff_plain;h=193a00fe39a31c25dcc480be6ca7be2b4eeed0ed;p=fs%2Flustre-release.git

- small changes to name2dev:
  Usage:
    obdctl > attach osc THEOSC
    obdctl > quit
    mount -t lustre_lite -o device=`obdctl name2dev THEOSC` none /mnt/lustre

- free a tiny leak
- temporary fix to runfailure-net
- also add to obdctl the setting of an environment variable when
  setting the name of a device.  Not clear yet if this is useful.
