Default multipath-tools/multipath mpath_wait multipath ...

CVSROOT: /cvs/dm
Module name: multipath-tools
Branch: RHEL5_FC6
Changes by: bmarzins@sourceware.org 2010-08-23 22:06:59

Modified files:
multipath : mpath_wait multipath.rules

Log message:
Fix for bz #568127. mpathwait will now wait for /dev/mapper/<mutipath_dev_name>
to be created before calling kpartx on it. This fixes a race condition. Not
applicable upstream.
