Otavio,
Tried to build this locally and got the following failure with

So I am going to hold off on this patch set until you can resolve this.
Yes; this is becase the linux-yocto seems to not have been updated to
3.10.13; so in fact it is failing to build to avoid people to
trigger the deadlock.
The change which introduces this in lttng-modules is:
http://git.lttng.org/?p=lttng-modules.git;a=commit;h=2aecb9b1cbb63f6c524ad9195d8fd06299ef9296
I can update this patch as 2.3.3 has been released and it includes the
3.12 fixes but please check when linux-yocto will be updated so we can
fix it.
Saul: What board are you building ? I've had linux-yocto on 3.10.17
for over a week
now.
As mentioned above this is for genericx86, so maybe not all the BSPs are
updated yet.
Buried in the context, sorry about missing that.
Yes, I'm about to update the reference boards, but there's a install
error that I'm fixing first, but I'll have the series out by end of day.
I just sent the update for this (cc'd [email protected]), but I haven't
seen it loop around.
If you didn't get the patch, let me know and I'll try again.
I have sent the new patch version.
It does the update to the 2.3.3 which include all the previous
backported patches.
This should be considered for Dora as well as it fixes the deadlock
and building with 3.12 kernels.
Hi Otavio, thanks for suggesting this for dora, but dora's kernel is 3.10.11,
and this is an update for lttng-modules, I'm not sure whether dora needs this.
Add Saul in the CC list.
// Robert
