The problem is this text in sysfs-kernel-mm-cma: > Each CMA heap subdirectory (that is, each > /sys/kernel/mm/cma/ directory) contains the > following items: When scripts/get_abi.pl sees the /sys/kernel/mm/... string it wants to turn it into a link to the matching ABI entry; at that point, the collides with the Sphinx directive and you get that totally useless warning. I think this is a bug in get_abi.pl. Honestly I wonder if all these cross-links are needed at all; if they truly are, then we shouldn't be making bogus ones. Mauro, how hard would it be to make this do the right thing? Thanks, jon
