There is an error when use disk monitor on btrfs:
WARNING: The free inode of rootfs is running low (0.000K left)
ERROR: Immediately abort since the disk space monitor action is "ABORT"!

This is beucase some fs formats' statvfs.f_files (inodes) is zero, thus
the statvfs.f_favail (free inodes) is zero, too, this a feature of the
fs, we disable the inode checking for such a fs.
