Subject: lib: pool_alloconly_destroy() optimization - Don't clear the last block before free
X-Git-Tag: 2.3.18~63
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4a74574d3934bf6120d9ca9479cb4275998b365c;p=thirdparty%2Fdovecot%2Fcore.git

lib: pool_alloconly_destroy() optimization - Don't clear the last block before free

The block is going to be freed, so there's no need to clear it.
(The clearing still happens if clean_frees=TRUE.)
