Subject: process-util: replace PTR_TO_PID() and PID_TO_PTR macro by inline functions
X-Git-Tag: v237~37^2~8
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=bc2fcf7f7a7388f7c5656b8c3f82c8816bf0590f;p=thirdparty%2Fsystemd.git

process-util: replace PTR_TO_PID() and PID_TO_PTR macro by inline functions

This way we gain some typesafety at no cost.
