Subject: [PATCH 08/10] scsi_dh: Remove dm_pg_init_complete
From: Chandra Seetharaman <sekharan@xxxxxxxxxx>
This patch just removes the dm layer's path initialization completion
routine. This is separated from the other patch(scsi_dh: Use SCSI
device handler in dm-multipath) Just to make that patch more readable.
