This year, we only had two scribes from LWN.net, not three, so there
won't be any coverage of the IO track when we split into three tracks.
To cover for that, here are my notes of the four separated sessions

The driver was calling scsi_scan_host before enabling interrupts.
This has gone unnoticed except for customers running in intx mode.
Calling scsi_scan_host before interrupts are enabled causes

This is another attempt to avoid a regression in wwn_to_u64()
after that started using get_unaligned_be64(), which in turn
ran into a bug on gcc-4.9 through 6.1.
As part of the problem is how __builtin_constant_p gets evaluated

The qla1280 driver sets the scsi_host_template's can_queue field to 0xf
which results in an allocation failure when allocating the block layer tags
for the driver's queues. This was introduced with the change for host wide
tags in commit 64d513ac31b - "scsi: use host wide tags by default".
