This is a note to let you know that I've just added the patch titled
staging: usbip: bugfix for stack corruption on 64-bit architectures
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-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.

Subject: staging: usbip: bugfix for stack corruption on 64-bit architectures
Previously a 6 byte array (buf) was erroneously cast to a 8 byte long
(event_bits) on 64-bit architectures which caused a stack corruption.
