There could be multiple userspace entities creating/destroying/
recoverying sessions and also the kernel's iscsi drivers could
be doing this too. If the userspace apps do try to manage the kernel

This patch fixes the problem by just exporting the pid of
the entity that created the session. Userspace programs like
iscsid, iscsiadm, iscsistart, qlogic's tools, etc, can then

[SCSI] mpt2sas: Fix possible integer truncation of cpu_count

When computing reply_queue_count (the number of MSI-X vectors to use),
the driver does

ioc->reply_queue_count = min_t(u8, ioc->cpu_count,
    ioc->msix_vector_count);

However, on a big machine, ioc->cpu_count could be outside the range
that fits in a u8; eg a system with 256 CPUs will end up
reply_queue_count set to 0.

Fix this by calculating the minimum as ints and then letting the

The amount of memory required for tracking chain buffers is rather

the number of host credits is limited to 30,000 IOs. However this

Detection of Dead IOC has been done in fault_reset_work thread.

If IOC Doorbell is 0xFFFFFFFF, it will be detected as non-operation/DEAD IOC.
When a DEAD IOC is detected, the code is modified to remove that IOC and
all its attached devices from OS.
The PCI layer API pci_remove_bus_device() is called to remove the dead IOC.

[SCSI] be2iscsi: cleanup a min_t() call

"sense_len" was declared as int type but actually it only stores a
u16 value that comes from hardware.  The cast to u16 in min_t()
confuses static analysis because it truncates the int to u16 so I've
fixed the declaration to reflect that "sense_len" is just a u16.

Also there was a call to cpu_to_be16() which I've changed to
be16_to_cpu().  The functions are equivalent, but obviously the
hardware is big endian and we're doing the min_t() comparison on CPU
endian values.

This whole patch is just a cleanup and doesn't affect how the code
works.

to all outstanding SCSI cmds in the xmit queue.  This will set

In the bnx2i SCSI response processing path, only the task was being checked

If there are outstanding SCSI cmd responses pending for process, the
