Test that doing a direct IO write against a file range that contains one prealloc extent and one compressed extent works correctly. From the linux kernel 4.0 onwards, this either triggered an assertion failure (leading to a BUG_ON) when CONFIG_BTRFS_ASSERT=y or resulted in an arithmetic underflow of an inode's space reservation for write operations. That issue is fixed by the following linux kernel patch: "Btrfs: fix extent accounting for partial direct IO writes" Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
