- all freelists converted to pools - initialization of structure members in certain cases where code was relying on specific allocation and usage properties to keep structures in a "known state" (that doesn't work with pools!). - make most pool_get() be "PR_WAITOK" until they can be analyzed further, and/or have proper error handling added. - all RF_Mallocs zero the space returned, so there is no difference between RF_Calloc and RF_Malloc. In fact, all the RF_Calloc()'s do is tend to do is get things horribly confused. Make RF_Malloc() the "general memory allocator", with RF_MallocAndAdd() the "general memory allocator with allocation list". - some of these RF_Malloc's et al. are destined to disappear. - remove rf_rdp_freelist entirely (it's not used anywhere!) - remove: #include "rf_freelist.h" - to the files that were relying on the above, add: #include "rf_general.h" - add: #include "rf_debugMem.h" to rf_shutdown.h to make it happy about the loss of: #include "rf_freelist.h". This shrinks an i386 GENERIC kernel by approx 5K. RAIDframe now weighs in at about 162K on i386.
