No idea really - this seems so far away from the code touched, and there
are no obvious signs for a memory scamble from another object touched
that I think if it really bisects down to that issue it must be a timing
But reading Bart's message again: Did you actually bisect it down
to the is commit? Or just test the whole tree? Between the 4.10-rc5
merge and all the block tree there might a few more likely suspects
like the scsi bdi lifetime fixes that James mentioned.
