Hello!

I recently have discovered problem with check_disk module.
It always shows "OK" even if your free space less than critical.

Example:
# df -k /var
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/vinum/var 33646567 28453984 2500858 92% /var

# ./check_disk -w 20 -c 10 /var
DISK OK [2500849 kB (8%) free on /dev/vinum/var]

I did some research and here is the patch.
