It would be useful if btrfs-progs had a USE flag to set the --enable-experimental configure flag, as some of the tests in https://github.com/kdave/xfstests rely on this.
See https://github.com/gentoo/gentoo/pull/37918
You can set EXTRA_ECONF="--enable-experimental" already.
(In reply to Paul Zander from comment #2) > You can set EXTRA_ECONF="--enable-experimental" already. Thanks, but I think this really ought to be a USE flag. There's also the issue that it doesn't install btrfs-corrupt-block by default, which xfstests also needs. My patch fixes both of these.
