Hi Anand,

You mean _has_fs_sysfs_attr()? however, it forces to check first parameter $dev
w/ block device type:

	if [ ! -b "$dev" -o -z "$attr" ];then
		_fail "Usage: _has_fs_sysfs_attr <mounted_device> <attr>"
	fi

How about this?

f2fs)
    local feat_file="/sys/fs/f2fs/features/fserror"
    if [ -f "$feat_file" ] && [ "$(cat "$feat_file")" = "supported" ]; then
        return 0
    fi
    ;;
