. traded a complex misaligned memory allocation scheme in the make_hist function for a simple aligned scheme. plus memory allocation increases are globally defined. . changed 1 parameter for procps_pids_stacks_sort() to better reflect the 'array of pointers', not an address of a pointer as is used with guys such as 'new/unref'. . the pids_reap struct was changed slightly to make it more reflective of it's actual implementation details. . the Item_table member .mustfree is now .needfree and that .makehist was now made .needhist for consistency. . reduced the number of separate 'return NULL;' source statements in that primary procps_pids_reap() routine. . ensured consistent reference to sizeof(void *) & not occasional reference to sizeof(void*) without a space. . rather than enable/disable validate_stacks via a #if in the function body, it is now handled via a #define. . some comments in the procps_pids_reset function were adjusted to reflect this current implementation. shown originally, they reflected an aborted attempt to avoid a testing aberration not fully understood at the time. . added a summary of the memory overhead cost of HST_t processing to that UNREF_RPTHASH output at unref time. . a 'PIDs at max depth:' portion of that UNREF_RPTHASH enabled #define is now published only when the maximum depth of hash table entry chains exceed depths of one.
