This is an early request for comments. The patch set serves as a zfcp preparation step for Hannes' series "[PATCH 00/47] SCSI EH argument reshuffle part II" http://www.spinics.net/lists/linux-scsi/msg111165.html or http://marc.info/?l=linux-scsi&m=150091945302995&w=2 The series is based on 18 preceding zfcp patches, including some stable regression bugfixes for zfcp tracing. Hence it might not apply cleanly. However, we plan to post the 18 preceding patches soon for integration and I would like to get those in first. Please do not apply to any tree that will merge into upstream yet, as it's not ready for prime time. It only builds (after each patch; sparse and checkpatch clean) but it has not seen any function testing yet. There are still some open questions: * Search victim scsi_device in target_reset_handler just to get a LUN? (Even if we do, zfcp_fsf_fcp_handler_common() should not print that LUN!) http://www.spinics.net/lists/linux-scsi/msg111164.html http://www.spinics.net/lists/linux-scsi/msg111166.html * Exact rport blocking logic in host_reset_handler. http://www.spinics.net/lists/linux-scsi/msg111165.html Steffen Maier (9): zfcp: drop unsuitable scsi_cmnd usage from SCSI traces for scsi_eh / TMF zfcp: decouple TMF response handler from scsi_cmnd zfcp: split FCP_CMND IU setup between SCSI I/O and TMF again zfcp: decouple FSF request setup of TMF from scsi_cmnd zfcp: decouple SCSI setup of TMF from scsi_cmnd scsi: fc: start decoupling fc_block_scsi_eh from scsi_cmnd zfcp: use fc_block_rport for TMFs and host reset to decouple from scsi_cmnd zfcp: fix waiting for rport(s) unblock in eh_host_reset_handler zfcp: decouple our scsi_eh callbacks from scsi_cmnd drivers/s390/scsi/zfcp_dbf.c | 51 ++++++++++++------- drivers/s390/scsi/zfcp_dbf.h | 26 +++++++--- drivers/s390/scsi/zfcp_ext.h | 12 +++-- drivers/s390/scsi/zfcp_fc.h | 24 ++++++--- drivers/s390/scsi/zfcp_fsf.c | 106 +++++++++++++++++++++++++-------------- drivers/s390/scsi/zfcp_scsi.c | 105 +++++++++++++++++++++++++++++--------- drivers/scsi/scsi_transport_fc.c | 31 ++++++++++-- include/scsi/scsi_transport_fc.h | 1 + 8 files changed, 252 insertions(+), 104 deletions(-) -- 2.11.2
