Patch sent to rh-kernel list: scsi_dh_emc: Set req->flags consistently in all scsi_dh_* modules none

Description Dave Wysochanski 2011-01-18 03:12:38 UTC
Other scsi_dh_* modules in RHEL5 set req->flags with broken out failfast bits.  scsi_dh_emc upstream does this as well, so make RHEL5 consistent with upstream and other scsi_dh_* modules in RHEL5.
