btrfs-convert convert FS with latest default features enabled, and if the kernel is down-rev and does not support a latest feature then mount fails, as expected. This patch disables default features based on the running kernel. Signed-off-by: Anand Jain <anand.jain@oracle.com> --- btrfs-convert.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-)
