From: millert Date: Mon, 19 Jan 2015 18:01:13 +0000 (+0000) Subject: Kill loadavg.h and just use the fscale value directly. X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=96fc89728e0feb2a443225e9187fe3fbf0756fa8;p=openbsd Kill loadavg.h and just use the fscale value directly. There's no need for crazy casts of p_pctcpu in ORDERKEY_PCTCPU since kinfo_proc exports it as uint32_t.
