From 327e5dab6dd8559ba28739ec8873350d7b5bb080 Mon Sep 17 00:00:00 2001 From: Quentin Monnet Date: Fri, 30 Nov 2018 16:25:44 +0000 Subject: tools: bpftool: use "/proc/self/" i.o. crafting links with getpid() The getpid() function is called in a couple of places in bpftool to craft links of the shape "/proc//...". Instead, it is possible to use the "/proc/self/" shortcut, which makes things a bit easier, in particular in jit_disasm.c. Do the replacement, and remove the includes of from the relevant files, now we do not use getpid() anymore.
