It filters the filesystems against a list of types:

#define VALID_FS_TYPES {"adfs", "affs", "befs", "bfs", "efs", "ext2", \
                        "ext3", "vxfs", "hfs", "hfsplus", "hpfs", "jffs", \
                        "jffs2", "minix", "msdos", "ntfs", "qnx4", "ramfs", \
                        "rootfs", "reiserfs", "sysv", "v7", "udf", "ufs", \
                        "umsdos", "vfat", "xfs", "jfs", "nfs"}

The dot on the end was intentional:

statgrab fs.

Although it'll only return what sg_get_fs_stats() does. It's just a bit
easier to test different versions of libstatgrba than writing your own
code.
