From 78b8fbf4fc51ce2d8aac4d1b12e77d8fd19dfebf Mon Sep 17 00:00:00 2001 From: Steffen Maier Date: Fri, 28 Jul 2017 12:30:55 +0200 Subject: [PATCH] scsi: zfcp: fix missing trace records for early returns in TMF eh handlers commit 1a5d999ebfc7bfe28deb48931bb57faa8e4102b6 upstream. For problem determination we need to see that we were in scsi_eh as well as whether and why we were successful or not. The following commits introduced new early returns without adding a trace record: v2.6.35 commit a1dbfddd02d2 ("[SCSI] zfcp: Pass return code from fc_block_scsi_eh to scsi eh") on fc_block_scsi_eh() returning != 0 which is FAST_IO_FAIL, v2.6.30 commit 63caf367e1c9 ("[SCSI] zfcp: Improve reliability of SCSI eh handlers in zfcp") on not having gotten an FSF request after the maximum number of retry attempts and thus could not issue a TMF and has to return FAILED.
