Commit 88263208dd ("scsi: qla2xxx: Complain if sp->done() is not called
from the completion path") introduced the WARN_ON_ONCE in
qla2x00_status_cont_entry(). The assumption was that there is only one
status continuations element. According to the firmware documentation it is
possible that multiple status continuations are emitted by the firmware.

This patch updates log message which indicates number of vectors used by
the driver instead of displaying failure to get maximum requested
vectors. Driver will always request maximum vectors during
initialization. In the event driver is not able to get maximum requested
vectors, it will adjust the allocated vectors. This is normal and does not
imply failure in driver.

Avoid code duplication between qla2x00_alloc_offload_mem() and
qla2x00_alloc_fw_dump() by moving the FCE and EFT buffer allocation and
initialization to separate functions. Cleanly track failure and success by
making sure that the ha->eft, ha->fce and respective eft_dma, fce_dma
members are set if and only if the buffers are properly allocated and
initialized. Avoid pointless buffer reallocation. Eliminate some goto
statements. Make sure the fce_enabled flag is cleared when the FCE buffer
is freed.

In qla2x00_alloc_fw_dump(), an existing EFT buffer (e.g. from previous

re-allocated, but without setting the eft and eft_dma fields to the new

the latter function directly. Remove the event member from the event_arg

The LIO core requires that the target driver callback functions
.queue_data_in() and .queue_status() call target_put_sess_cmd() or
transport_generic_free_cmd(). These calls may happen synchronously or
asynchronously. Make sure that one of these LIO functions is called in case
a command has been aborted. This patch avoids that the code for removing a
session hangs due to commands that do not make progress.

Instead of allocating a struct srb dynamically from inside .queuecommand(),
set qla2xxx_driver_template.cmd_size such that struct scsi_cmnd and struct
srb are contiguous. Do not call QLA_QPAIR_MARK_BUSY() /
QLA_QPAIR_MARK_NOT_BUSY() for SRBs associated with SCSI commands. That is
safe because scsi_remove_host() is called before queue pairs are deleted
and scsi_remove_host() waits for all outstanding SCSI commands to finish.
