This is a note to let you know that I've just added the patch titled
USB: uas: heed CAPACITY_HEURISTICS
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-testing branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will be merged to the usb-next branch sometime soon,
after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

There is no need to ignore this flag. We should be as close
to storage in that regard as makes sense, so honor flags whose
cost is tiny.
