New Revision: 196244
URL: http://svn.freebsd.org/changeset/base/196244
Log:
- Avoid overflowing the swap size counters in human-readable mode
by introducing the new CONVERT_BLOCKS macro which operates on
sizes already converted to number of blocks. With this macro
it is not longer needed to perform needless multiplication by
blocksize just to divide on it later in CONVERT macro.
