Motivation and Context

buildbot/Kernel.org failed with errors like the following:

In file included from ./include/trace/define_trace.h:102:0,
                 from ./include/zfs/os/linux/zfs/sys/trace_arc.h:385,

           ~^
           %llx

It is likely caused by commit 4938d01db7 which changed zio_flag from enum to uint64_t.

Description

Use the suggested format %llx.

How Has This Been Tested?

No, buildbot will tell.

@youzhongyang You beat me to this. I had caught this late yesterday and promised @behlendorf that I would tackle it this morning.

Your solution should work.
