Michael,
Thank you for your swift response. However, for the first part, I'm not
sure what it means by "using" the full kernel source. How would I use it
with lttng-modules?
As for the quick hack part, I grabbed the kernel source and copied the
mount.h onto the folder you mentioned, and it did not help. I don't
expect lttng to automatically find that file and use it; also there are
no other header files in the package build directory. Could you kindly
give us more instructions?
Thanks,
Mohammad
The lttng modules are shipped in Ubuntu as a dkms package which means
they are built directly on your machine for each kernel version you
install. So after adding the required file in your headers you'll need
to rebuild the modules with dkms and unload / reload them in your
running kernel or just reboot the machine.
To rebuild all installed dkms modules for the current kernel:
sudo dkms autoinstall
