sys/sys malloc.h
Log:
Force the "calls" count for malloc types to be 64 bit where it keeps track
of the number of times a particular type has been used. It's rather easy
to overflow. One site I'm looking at seems to do it in a matter of days.
On the Alpha this is a no-op since 'long' is 64 bit already. The sole
user of this interface seems to be vmstat -m and friends which will need
a recompile. The overheads of using a 64 bit int should be pretty light
as the kernel just does "calls++" type operations and that's it.
