In the *_done() functions, instead of returning early if sp->ref_count >= 2, only decrement sp->ref_count. In qla2xxx_eh_abort(), instead of deciding what to do based on the value of sp->ref_count, decide which action to take depending on the completion status of the firmware abort. Remove srb.cwaitq and use srb.comp instead. In qla2x00_abort_srb(), call isp_ops->abort_command() directly instead of calling qla2xxx_eh_abort().

Since qla24xx_async_abort_cmd() is only called from inside qla_init.c, declare that function static. Reorder a few functions to avoid that any forward declarations are needed. Cc: Himanshu Madhani <hmadhani@marvell.com> Cc: Giridhar Malavali <gmalavali@marvell.com> Signed-off-by:

All callbacks from the target core into the qla2xxx driver and also all I/O completion functions are serialized per command. Since .cmd_sent_to_fw and .trc_flags are only modified from inside these functions it is not necessary to protect it with locking. Remove the superfluous locking.

Since the previous patch removed the only statement that sets qla_tgt_cmd.released, remove the code that depends on that member variable being set and the member variable itself. Cc: Himanshu Madhani <hmadhani@marvell.com> Cc: Giridhar Malavali <gmalavali@marvell.com> Signed-off-by:

The previous patch guarantees that a command is only released after the firmware has finished processing it. Hence complain if a command is released that is owned by the firmware. Cc: Himanshu Madhani <hmadhani@marvell.com> Cc: Giridhar Malavali <gmalavali@marvell.com> Signed-off-by:

Remove the function qlt_abort_cmd_on_host_reset() because it can do the following, all of which can cause a kernel crash: - DMA unmapping while DMA is in progress. - Call target_execute_cmd() while DMA is in progress. - Call transport_generic_free_cmd() while the LIO core owns a command. Instead of trying to abort a command asynchronously, set the 'aborted' flag and handle the abort after the hardware has passed control back to the tcm_qla2xxx driver.

Implementations of the .write_pending() callback functions must guarantee that an appropriate LIO core callback function will be called immediately or at a later time. Make sure that this guarantee is met for aborted SCSI commands.

The test "if (!cmd)" is not useful because it is guaranteed that cmd != NULL. Instead of testing the cmd pointer, rely on the tag to decide whether or not command allocation failed.

All qlt_send_term_imm_notif() callers pass '1' as second argument to this function. Hence remove the (broken) code that depends on that second argument having another value. Add a pr_debug() statement that prints rc to avoid that the compiler would complain that rc has been set but is not used.

The current order for freeing memory is as follows: - struct crc_context itself. - struct crc_context member pointers.
