| 207.Sh BUGS 208It is not possible to guard allocations that really expect theirselves to be 209allocated from 210.Xr uma 9 , 211utilizing additional interfaces apart from 212.Fn uma_zalloc 213and 214.Fn uma_free , 215for example 216.Fn uma_find_refcnt . 217For the moment of writing only 218.Xr mbuf 9 219cluster zones belong to that kind of allocations. 220Attempt to guard them would lead to kernel panic. |
