Verify that btrfs send is able to replicate xattrs larger than PATH_MAX. This is possible if the b+tree leaf size is larger than 4Kb (mkfs.btrfs's default is max(16Kb, PAGE_SIZE) as of btrfs-progs v3.12, and max(4Kb, PAGE_SIZE in older versions). This issue is fixed by the following linux kernel btrfs patch: Btrfs: send, use the right limits for xattr names and values Signed-off-by: Filipe David Borba Manana <fdmanana@gmail.com> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
