Now it's ready to move the mempool based SG chained allocator code from SCSI driver to lib/sg_pool.c, which will be compiled only based on a Kconfig symbol CONFIG_SG_POOL. SCSI selects CONFIG_SG_POOL. Reviewed-by:

Rename SCSI_MAX_SG_SEGMENTS to SG_CHUNK_SIZE, which means the amount we fit into a single scatterlist chunk. Rename SCSI_MAX_SG_CHAIN_SEGMENTS to SG_MAX_SEGMENTS. Will move these 2 generic definitions to scatterlist.h later. Reviewed-by:

When we are in connection recovery and the internal command timer on a request pops, either the scsi_cmnd->device or scsi_cmnd->device->host back pointers may be NULL as the device that the command that the request was submitted on may have been subsequently reaped due to the connection recovery. This can cause one or both of the pointers above to be NULL and cause a system crash if we try to return the command to the midlayer. Instead, double check the pointers before the return to the midlayer so as to prevent the crash and let the upper layers finish the session recovery and rediscover the device. Signed-off-by:

Now that we've done a more comprehensive fix with the intermediate target state we can remove the previous hack introduced with commit 90a88d6e ("scsi: fix soft lockup in scsi_remove_target() on module removal"). Signed-off-by:

Add intermediate STARGET_REMOVE state to scsi_target_state to avoid running into the BUG_ON() in scsi_target_reap(). The STARGET_REMOVE state is only valid in the path from scsi_remove_target() to scsi_target_destroy() indicating this target is going to be removed. This re-fixes the problem introduced in commits bc3f02a7 ("[SCSI] scsi_remove_target: fix softlockup regression on hot remove") and 40998193 ("scsi: restart list search after unlock in scsi_remove_target") in a more comprehensive way.

While HBA reset is in progress, if IO/TM completion is received for the same IO then IO/TM completion path releases the driver private resources associated with IO. This fix prevents releasing the resources in IO and TM completion path if HBA reset is in progress. Signed-off-by:

- On posting an IO to the firmware, adapter generates an interrupt. Due to hardware issues, sometimes the adapter fails to generate the interrupt. This behavior skips updating transmit queue- counters, which in turn causes the queue full condition. The fix addresses the queue full condition. - The fix also reserves a slot in transmit queue for hba reset. when queue full is observed during IO, there will always be room to post hba reset command.

The default rpi completion handler does back to back puts to force the removal of the ndlp. This ends up calling lpfc_unreg_rpi after the reference count is at 0.

When issuing I/O we check if rport is online through libfc rport_lookup() function which needs to be protected by mutex lock that cannot acquired in I/O context. The change is to use midlayer remote port s dd_data which is preserved until its devloss timeout and no protection is required. The the scsi_cmnd error code is expected to be in the left 16 bits of the result field. Changed to correct this. Fnic driver version changed from 1.6.0.20 to 1.6.0.21 Signed-off-by:
