Subject: lib: data-stack - mem_block_alloc() - Set stack_block.left to final value immediately
X-Git-Tag: 2.3.16~253
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=7b1c81b369dda0f1c84268d299d1f5ffd17c1050;p=thirdparty%2Fdovecot%2Fcore.git

lib: data-stack - mem_block_alloc() - Set stack_block.left to final value immediately

There's no need to first set it to 0 and then have the caller change it
again.
