07f490ac97 Document uma_find_refcnt(). 2013-03-21 16:04:34 +00:00

2f891cd504 Implemented uma_zone_set_warning(9) function that sets a warning, which 
will be printed once the given zone becomes full and cannot allocate an
item. The warning will not be printed more often than every five minutes.

All UMA warnings can be globally turned off by setting sysctl/tunable
vm.zone_warnings to 0.

6b99842ada Globally replace u_int*_t from (non-contributed) man pages. 
The reasoning behind this, is that if we are consistent in our
documentation about the uint*_t stuff, people will be less tempted to
write new code that uses the non-standard types.

I am not going to bump the man page dates, as these changes can be
considered style nits. The meaning of the man pages is unaffected.

1c6cae9711 Change uma_zone_set_max to return the effective value of "nitems" after 
rounding. The same value can also be obtained with uma_zone_get_max, but this
change avoids a caller having to make two back-to-back calls.

c4ae7908a7 - Simplify implementation of uma_zone_get_max. 
- Add uma_zone_get_cur which returns the current approximate occupancy of
  a zone. This is useful for providing stats via sysctl amongst other things.
