It was reported in https://bugzilla.redhat.com/show_bug.cgi?id=1321033,
that the qla1280 driver sets the scsi_host_template's can_queue field
to 0xfffff which results in an allocation failure when allocating the
block layer tags for the driver's queues like the one shown below:

The change looks fine, I see its hard-coded to 32 in qla1280_set_defaults()
Would it be better to create a #define like other drivers and use that in both.
Also did the below patch resolve this for the bug reporter.
I ask because if I check 4.3 it was also set to the same value of 0xfffff and that is reported as working.
So other changes in 4.4 must be "abusing" this high value.

Yes, that's probably a reasonable idea, I'll re-send.

I think it was introduced with commit 64d513ac31b - "scsi: use host wide
tags by default". Since this commit scsi_add_host_with_dma() directly calls
blk_init_tags() instead of scsi_init_shared_tag_map(). The qla1280 driver
has never set up the block tags though, so the bogus value was not a problem.
That at least is my analysis, feel free to correct my assumptions.

Yes, that's probably a reasonable idea, I'll re-send.

I think it was introduced with commit 64d513ac31b - "scsi: use host wide
tags by default". Since this commit scsi_add_host_with_dma() directly calls
blk_init_tags() instead of scsi_init_shared_tag_map(). The qla1280 driver
has never set up the block tags though, so the bogus value was not a problem.
That at least is my analysis, feel free to correct my assumptions.
