Thanks again for your reply,
To be specific, I did exactly this:
- Install linux source code, then copy the mentioned file to the folder
using: cp
/usr/src/linux-headers-5.4.0-59/fs/mount.h /lib/modules/$(uname -r)/build
The path to the header has to stay the same, so you would need to copy
it to '/lib/modules/$(uname -r)/build/fs'.
The rest of the steps seem fine.
One thing you can do if it still doesn't work, is modify 'Makefile' and
'Kbuild.common' in the lttng-modules source directory and remove the
conditions on 'mnt_ns_dep'. That would make the build fail when
'fs/mount.h' isn't found and may help you find the cause.
- Run sudo dkms autoinstall (I also did reboot)
- Create the session and attempt to add the context
However, I'm getting the same error.
