Hi Gustavo,

After merging the bluetooth tree, today's linux-next build
(x86_64_allmodconfig) failed like this:

net/bluetooth/hci_sock.c: In function 'hci_sock_cmsg':
net/bluetooth/hci_sock.c:738:8: error: 'COMPAT_USE_64BIT_TIME' undeclared (first use in this function)

Caused by commit aebb77ca6ad1 ("compat: Use COMPAT_USE_64BIT_TIME in the
Bluetooth subsystem").  That symbol doesn't exist anywhere in linux-next ...

I have used the bluetooth from next-20120221 for today.

P.S. that commit is supposedly authored by H. J. Lu but does not contain
a Signed-off-by from him.

That patch series was meant to go in as a group, because all of the
subsequent patches depend upon patches earlier in the series.

There is zero reason you should have applied that patch into your
bluetooth subsystem tree.  The fact that it wasn't adequately build
tested either I find quite troubling.

Lots of red cards for the bluetooth maintainers today.
