Hi Bruce,

The world build for genericx86 tripped over a compilation failure for
lttng-modules:

There are several others. Quickly reproducible with:

$ bitbake lttng-modules

Is this a known issue with the 3.10 kernel?

Known at the moment ... no, since my builds didn't trigger lttng modules
to be built. And actually, it's one of the reasons I prefer all modules
to be in-tree versus out of tree :)

But it's also not something hard to fix. When LTSI content becomes available we'll have an in tree version again, but in the mean time
we can just patch lttng modules, via an uprev or bug fix.

I wouldn't hold the merge on this (we can't hold it on everything), so
my suggestion is to open a bug and we can have a look tomorrow.

Bruce



Thanks,
