The order (it's a shall, but hard to dictate after the fact) is given in FC-SCM - kind of. SCM indicates what shall be implemented, lists it as (a), (b), (c), but actually doesn't say it has to be in that order. The only hard requirement, called out in FCP-4, is that you must register your FC-4 Type (via RFT_ID) before registering FC-4 Type Features (via RFF_ID), which makes sense. We obviously violated this and there were some switches (or newer fw in them) that enforced it. The other rule of thumbs are: register your data with the switch first, then register for SCRs, then do queries about the fabric, with the SCRs telling you of changes post the queries.

由 Seymour, Shane M 提交于
This patch implements tape statistics in the st module via sysfs. Current no statistics are available for tape I/O and there is no easy way to reuse the block layer statistics for tape as tape is a character device and does not have perform I/O in sector sized chunks (the size of the data written to tape can change). For tapes we also need extra stats related to things like tape movement (via other I/O). There have been multiple end users requesting statistics including AT&T (and some HP customers who have not given permission to be named). It is impossible for them to investigate any issues related to tape performance in a non-invasive way.

Only include SCSI initiator header files in target code that needs these header files, namely the SCSI pass-through code and the tcm_loop driver. Change SCSI_SENSE_BUFFERSIZE into TRANSPORT_SENSE_BUFFER in target code because the former is intended for initiator code and the latter for target code.

megaraid_sas : Modify return value of megasas_issue_blocked_cmd() and wait_and_poll() to consider command status returned by firmware This patch is rebased on top of recently sent 18 patches(submitted by me) for megaraid_sas driver. Change the return value of wait_and_poll() and megsas_issue_blocked_cmd() based on MFI_STAT returned by firmware for that command. Earlier driver always send return type based on command completion (but never check MFI_STAT_OK for that command), so even if command is failed by firmware still driver will return SUCCESS status from these functions wait_and_poll() and megsas_issue_blocked_cmd() and if caller of these functions does not check command status (MFI_STAT), then it may endup using invalid data returned in DMA buffers(one of the example is megasas_ld_list_query DCMD). Best thing to avoid this type of issue is do error handling and set proper return type from caller function wait_and_poll() and megsas_issue_blocked_cmd(). The change proposed in this patch will fix the regression introduced in patch- "90dc9d98 megaraid_sas : MFI MPT linked list corruption fix" inside function megasas_ld_list_query(). Prior to this MFI MPT linked list corruption fix patch, megasas_ld_list_query() function used to check DCMD status(returned by firmware) but with this linked list corruption fix patch, DCMD status will not be checked inside function megasas_ld_list_query() and introduced this issue of wrong data being used by function megasas_ld_list_query().
