When unloading and reloading the driver, the driver fails to recreate the lpfc root inode in the debugfs tree. The driver is incorrectly removing the lpfc root inode in lpfc_debugfs_terminate in the first driver instance that unloads and then sets the lpfc_debugfs_root global parameter to NULL. When the final driver instance unloads, the debugfs calls quietly ignore the remove on a NULL pointer. The bug is that the debugfs_remove call returns void so the driver doesn't know to correctly set the global parameter to NULL. Base the debugfs_remove of the lpfc_debugfs_root parameter on lpfc_debugfs_hba_count because this parameter tracks the fnX instance tracked per driver instance. Signed-off-by:

Currently IO resources are mapped 1 to 1 with RQ buffers posted Added logic to separate RQE buffers from IO op resources (sgl/iocbq/context). During initialization, the driver will determine how many SGLs it will allocate for NVMET (based on what the firmware reports) and associate a NVMET IOCBq and NVMET context structure with each one. Now that hdr/data buffers are immediately reposted back to the RQ, 512 RQEs for each MRQ is sufficient. Also, since NVMET data buffers are now 128 bytes, lpfc_nvmet_mrq_post is not necessary anymore as we will always post the max (512) buffers per NVMET MRQ. Signed-off-by:

During driver boot, a latency in the NVMET driver side causes the incoming NVMEI PRLI to get rejected by the NVMET driver. When this happens, the NVMEI driver runs out of PRLI retries. Bouncing the link does not fix the situation. If the NVMEI driver decides, on PRLI completion failures, to retry the PRLI, always decrement the fc4_prli_sent counter. This allows the PRLI completion to resolve to UNMAPPED when NVMET rejects the PRLI. Signed-off-by:

With 255 vports created a link trasition can casue a crash. When going through discovery after a link bounce the driver is using rpis before the cmd FCOE_POST_HDR_TEMPLATES completes. By doing that the next rpi bumps the rpi range out of the boundary. The fix it to increment the next_rpi only when the FCOE_POST_HDR_TEMPLATE succeeds. Signed-off-by:

Some external hard drives don't support the sync command even though the hard drive has write cache enabled. In this case, upon suspend request, sync cache failures are ignored if the error code in the sense header is ILLEGAL_REQUEST. There's not much we can do for these drives, so we shouldn't fail to suspend for this error case. The drive may stay powered if that's the setup for the port it's plugged into. Signed-off-by:

We store sc_cmd->cmnd[0] which is an unsigned char in io_log->op so this should also be unsigned char. The other thing is that this is displayed in the debugfs: seq_printf(s, "0x%02x:", io_log->op); Smatch complains that the formatting won't work for negative values so changing it to unsigned silences that warning as well.

When a device is unplugged from a SCSI controller, if the scsi_device is still in use by application layer, it won't get released until users close it. In this case, scsi_device_remove just set the scsi_device's state to be SDEV_DEL. But if you plug the disk just before the old scsi_device is released, then there will be two scsi_device structures in scsi_host->__devices. When the next unplug event happens, some low-level drivers will check whether the scsi_device has been added to host (for example the MegaRAID SAS series controller) by calling scsi_device_lookup(call __scsi_device_lookup) in function megasas_aen_polling. __scsi_device_lookup will return the first scsi_device. Because its state is SDEV_DEL, the scsi_device_lookup will return NULL, making the low-level driver assume that the scsi_device has been removed, and won't call scsi_device_remove which will lead to hot swap failure.

To select the appropriate shost template, the driver is issuing a mailbox command to retrieve the wwn. Turns out the sending of the command precedes the reset of the function. On SLI-4 adapters, this is inconsequential as the mailbox command location is specified by dma via the BMBX register. However, on SLI-3 adapters, the location of the mailbox command submission area changes. When the function is first powered on or reset, the cmd is submitted via PCI bar memory. Later the driver changes the function config to use host memory and DMA. The request to start a mailbox command is the same, a simple doorbell write, regardless of submission area. So.. if there has not been a boot driver run against the adapter, the mailbox command works as defaults are ok. But, if the boot driver has configured the card and, and if no platform pci function/slot reset occurs as the os starts, the mailbox command will fail. The SLI-3 device will use the stale boot driver dma location. This can cause PCI eeh errors. Fix is to reset the sli-3 function before sending the mailbox command, thus synchronizing the function/driver on mailbox location. Note: The fix uses routines that are typically invoked later in the call flow to reset the sli-3 device. The issue in using those routines is that the normal (non-fix) flow does additional initialization, namely the allocation of the pport structure. So, rather than significantly reworking the initialization flow so that the pport is alloc'd first, pointer checks are added to work around it. Checks are limited to the routines invoked by a sli-3 adapter (s3 routines) as this fix/early call is only invoked on a sli3 adapter. Nothing changes post the fix. Subsequent initialization, and another adapter reset, still occur - both on sli-3 and sli-4 adapters. Signed-off-by:
