I would like to make another point about why I am making this change
in case it is not clear. The queue full events are form
TRANS_TX_CREDIT_TIMEOUT_ERR and TRANS_TX_CLOSE_NORMAL_ERR errors in
the slot: I want the slot retried when this occurs, so I set status

Hello Hannes,
Thank you for your reply. I am on 4.4.2 kernel, is there any chance to commit
it in 4.4 as well? If not, could you send me diff for 4.4 kernel.

Hi Hannes,
How do you know that a request for an async scan is complete (I'm assuming that
you get add or change udev events)? Assuming that someone has manually started

Pegasus is a high performace hardware RAID solution designed to unleash

1. Add code to distinct SuperTrack and Pegasus series by sub device ID.
It should support backward compatibility.

1. Add hotplug support. Pegasus support surprise removal. To this end, I

2. Remove stex_hba_stop in stex_remove because we cannot send command to

This bug causes the wrong command to have its sense pointer overwritten,
which sometimes leads to a NULL pointer deref. Fix this by checking which
command is being requeued before restoring the scsi_eh_save data.
It turns out that some targets will disconnect a REQUEST SENSE command.

These patches fix some exception handling and autosense bugs that I
accidentally introduced in v4.5-rc1.
The error recovery and autosense code in these drivers has been unstable
for a long time. Despite that, v4.5-rc1 shows a regression in as much as
it exposes a bug in the aranym emulator. This

Commands subject to exception handling are to be returned to the scsi
mid-layer. Make sure that the various command pointers and command lists
in the low-level driver are correctly cleansed of affected commands.
This fixes some bugs that I accidentally introduced in v4.5-rc1 including
the removal
Calling NCR5380_select() from the abort handler causes various problems.
Firstly, it means potentially re-entering NCR5380_select(). Secondly, it
means that the lock is released, which permits the EH handlers to be
re-entered. The combination results in crashes. Don't do it.
Fixes: 8b00c3d5d40d ("
The list structures and related logic used in the NCR5380 driver mean that
a command cannot be queued twice (i.e. can't appear on more than one queue
and can't appear on the same queue more than once).
The abort handler must forget the command so that the mid-layer can re-use
it. E.g. the ML may s
The calls to NCR5380_transfer_pio() for DATA IN and DATA OUT phases will
modify cmd->SCp.this_residual, cmd->SCp.ptr and cmd->SCp.buffer. That
works as long as EH does not intervene, which became possible in
atari_NCR5380.c when I changed the locking to bring it closer to
NCR5380.c.
