From: Quentin Monnet Date: Wed, 14 Aug 2019 11:37:24 +0000 (+0100) Subject: tools: bpftool: compile with $(EXTRA_WARNINGS) X-Git-Tag: v5.4-rc1~131^2~62^2~43 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=a9436dca115d121d98e0b30f078f3294ce13fa18;p=linux.git tools: bpftool: compile with $(EXTRA_WARNINGS) Compile bpftool with $(EXTRA_WARNINGS), as defined in scripts/Makefile.include, and fix the new warnings produced. Simply leave -Wswitch-enum out of the warning list, as we have several switch-case structures where it is not desirable to process all values of an enum. Remove -Wshadow from the warnings we manually add to CFLAGS, as it is handled in $(EXTRA_WARNINGS).
