This is a note to let you know that I've just added the patch titled
usb: gadget: f_fs: resurect usb_functionfs_descs_head structure
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-linus 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 hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Even though usb_functionfs_descs_head structure is now deprecated,
it has been used by some user space tools. Its removel in commit
[ac8dde1: “Add flags to descriptors block”] was an oversight
leading to build breakage for such tools.
Bring it back so that old user space tools can still be build
without problems on newer kernel versions.
