talpa doesn't compile on ubuntu 17.04 linux 4.10

pastim

talpa doesn't compile since I upgraded to ubuntu 17.04.  This uses linux 4.10.

The last few lines of talpaselect.log are:

......
checking for linux/dcache.h... yes
checking for __d_path prototype... available
checking for exported __d_path... undetectable
checking for linux/dcache.h... yes

checking for __lookup_mnt_last address... configure: error: not found

Traceback (most recent call last):
File "talpa_select.py", line 2176, in _action
File "talpa_select.py", line 1074, in load

File "talpa_select.py", line 1910, in __try_build
File "talpa_select.py", line 1773, in checkConfigureErrors
SelectException: exc-configure-failed-freeversion

I believe that the __lookup_mnt_last address function has been removed from linux 4.9 - see https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.15

I also raised this as an Issue on talpa in github at https://github.com/sophos/talpa/issues/2

    I should add that I am using the autodeploy.sh script, so should have the very latest version.

    If any more information is needed please ask.  Here's the start of the talpaselect.log.

    Hello pastim,

    can't say if is notified when you raise an issue at github, but he gets notifications from the Community.

    Hi,

    I've raised a Jira ticket to add support for kernels 4.9 and 4.10 to Talpa.

    I'm afraid a quick look at that commit suggests it won't be trivial to do the update.

    Thanks.  I guessed that that sort of issue might be non-trivial to resolve.  No matter, at least it's in hand.

    I'm slightly puzzled as to why no one has seen it before.  Linux 4.9 was out at the end of last year.  Never mind.  :)

    We've managed to fix Talpa to work on 4.9 and 4.10 kernels for us. It's been pushed to github perforce branch.

    Thanks very much.  All seems OK - compiled, built and being used by Sophos-av.  If I have any comments I'll leave them on the github issue if that is OK.
