This is a note to let you know that I've just added the patch titled
USB: documentation: flags on usb-storage versus UAS
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.
