From 7c66e9a5e6b0459c619562c5ad321071e2767faa Mon Sep 17 00:00:00 2001 From: Joseph Gruher Date: Wed, 5 Jan 2011 16:00:20 -0500 Subject: [PATCH] [SCSI] scsi_dh_alua: fix submit_stpg return submit_stpg() will always return failure so alua_activate() will report failure via dm-multipath callback function. Even though the stpg fired successfuly dm-multipath does not know and always fails to change the valid path. By returning SCSI_DH_OK we're now skipping alua_activate()'s call to activate_complete 'fn'. But this is fine because stpg_endio() will call it via h->callback_fn().
