Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

2012-07-25T01:11:22Z

Pull first round of SCSI updates from James Bottomley: "The most important feature of this patch set is the new async infrastructure that makes sure async_synchronize_full() synchronizes all domains and allows us to remove all the hacks (like having scsi_complete_async_scans() in the device base code) and means that the async infrastructure will "just work" in future. The rest is assorted driver updates (aacraid, bnx2fc, virto-scsi, megaraid, bfa, lpfc, qla2xxx, qla4xxx) plus a lot of infrastructure work in sas and FC.

[SCSI] bnx2fc: Improve error recovery by handling parity errors

2012-07-20T07:58:23Z

During parity errors, the ramrods are not issued to FW. bnx2fc waits for the timeout value, and proceeds with cleaning up the IOs. Since we are already out-of-sync with FW, cleanup commands timeout too, and do not get the completion. This operation takes 36 secs for each session to upload causing huge delays. To fix this, bnx2fc now gets a PARITY_ERROR from cnic driver, and upon failure, the driver does not issue any commands to the FW and finishes the upload process sooner.

[SCSI] bnx2fc: Support interface creation on non-VLAN interface also.

2012-07-20T07:58:19Z

bnx2fc had an assumption that the fcoe interface will always start on the vlan dev. However, some switch implementations (Eg., HP virtual connect FlexFabric) expects the fcoe interface to be started on physical interface. Do not error out if the netdev is not a vlan dev.

[SCSI] bnx2fc: Reduce object size by consolidating formats

2012-07-20T07:58:17Z

Deduplication of formats and consolidating tests makes the object much smaller. Add bnx2fc_debug.c, add functions for a few logging functions (BNX2FC_IO_DBG, BNX2FC_TGT_DBG, BNX2FC_HBA_DBG). Use printf extension %pV. Add and use pr_fmt and pr_.

[SCSI] bnx2fc: use kthread_create_on_node

2012-07-20T07:58:14Z

Since bnx2fc_percpu_thread_create() creates percpu kthread, it makes sense to use kthread_create_on_node() to get proper NUMA affinity for kthread stack. Signed-off-by: Eric Dumazet Signed-off-by: Bhanu Prakash Gollapudi Signed-off-by: James Bottomley

[SCSI] libfc, fcoe, bnx2fc: cleanup fcoe_dev_stats

2012-07-20T07:31:47Z

The libfc is used by fcoe but fcoe agnostic, and therefore should not have any fcoe references. So renaming fcoe_dev_stats from libfc as its for fc_stats. After that libfc is fcoe string free except some strings for Open-FCoE.org.

[SCSI] fcoe, bnx2fc, libfcoe: SW FCoE and bnx2fc use FCoE Syfs

2012-05-23T08:43:13Z

This patch has the SW FCoE driver and the bnx2fc driver make use of the new fcoe_sysfs API added earlier in this patch series. After this patch a fcoe_ctlr_device is allocated with private data in this order. +------------------+ +------------------+ | fcoe_ctlr_device | | fcoe_ctlr_device | +------------------+ +------------------+ | fcoe_ctlr | | fcoe_ctlr | +------------------+ +------------------+ | fcoe_interface | | bnx2fc_interface | +------------------+ +------------------+ libfcoe also takes part in this new model since it discovers and manages fcoe_fcf instances. The memory allocation is different for FCFs. I didn't want to impact libfcoe's fcoe_fcf processing, so this patch creates fcoe_fcf_device instances for each discovered fcoe_fcf. The two are paired using a (void * priv) member of the fcoe_ctlr_device. This allows libfcoe to continue maintaining its list of fcoe_fcf instances and simply attaches and detaches them from existing or new fcoe_fcf_device instances.
