X-Git-Tag: 2.5.0-alpha~6710
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=46afd8fd2e7442c0b1d6e692d09e74f98f867c51;p=apache

improve dump_allocator, add dump_one_pool

- dump_one_pool dumps the size of a pool not including child pools
- dump_allocator now dumps the size of the memnodes and not the last used
  free size. Also dump the total size.
