This worked fine on another machine the other day, so I dug in and found that the only difference was an intermediate update to btrfs-progs 4.10. Sure enough: since 4.10 ctree.h includes , which is nowhere to be found in my package of linux-headers-4.10 (also not in 4.9). Simply copying sizes.h from the 4.9 kernel sources made everything work, but I'm curious whether this is actually correct - hence my question whether _should_ actually be installed? Is this a bug with Gentoo's kernel header package or a new problem with btrfs-progs? I don't see any good reason why sizes.h should not be installed, but wanted to verify since there are probably users of other distributions here as well. :) Thanks, Holger
