Subject: basic/mempool: mark mempool_enabled as _pure_
X-Git-Tag: v258.2~66
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=29cbe93ea5e845f6621c44dd73b0f3ebfbe7ddf4;p=thirdparty%2Fsystemd.git

basic/mempool: mark mempool_enabled as _pure_

The function internally does caching which means that the result must
always be the same, the definition of a pure function. The compiler might
be able to optimize some repeated calls to the function.

(cherry picked from commit 882dfbde1c3159689eabadfab430aa9c272af163)
