Is this a bug with > Gentoo's kernel header package or a new problem with btrfs-progs? That's a bug in btrfs-progs, the build tests do not cover that. There's a local copy of sizes.h that's supposed to be used. The patch was ported from kernel where linus/sizes.h is present but is probably not (yet) part of the public linux-headers. > 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. :) The build would fail on any distro. I'll commit a fix and update the tests so this gets caught early.
