commit:
The VPD page length parameter is not only used for the length,
but also to hold any error code. So it needs to be moved to an
integer.
And we should be resetting the default VPD page length after
each iteration so that we do not allocate overly large buffers.

Add a flag 'vpd_invalid' to the SCSI device to indicate that
the VPD data needs to be refreshed. This is required if either
a manual rescan is triggered or if the sense code INQUIRY DATA

Depending on whether we use extended or normal
CISS_REPORT_LUNS command, the returned data is either
8 or 24 bytes per LUN, and the code needs to take this
into account instead of just always assuming 24 bytes
per LUN. This would cause

This RFC provides a rough implementation of a mechanism to allow
userspace to attach protection information (e.g. T10 DIF) data to a

Since userspace can now pass PI buffers through to the block integrity

Hi,
I've got kernel panic on my box which works as FibreChannel initiator.
I was able to reproduce this panic by setting dev_loss_tmo=2 and
enabling/disabling ports every 5 seconds on the switch in 5 minutes. I
added some debug points in the kernel code and that's what I've got so far:
