[PATCH v3 5/8] scripts: add Linux .cocciconfig for coccinelle

From: Luis R. Rodriguez
Date: Tue Jun 21 2016 - 15:23:44 EST


Help Coccinelle when used against Linux with a set of sensible defaults
options for Linux. This hints to coccinelle git can be used for 'git grep'
queries over coccigrep. A timeout of 200 seconds should suffice for now.

If you use idutils you can override for 'make coccicheck' by using the
SPFLAGS option as follows:

First build the index, for example:
mkid -s

Pick the cocci file you wnat to work with:
export COCCI=scripts/coccinelle/misc/irqf_oneshot.cocci

Then run coccicheck:
$ make coccicheck V=1 MODE=report SPFLAGS="--use-idutils ID"

Coccinelle supports reading .cocciconfig from different directories,
the later one overriding the previous reads in the following order:

o Your current user's home directory is processed first
o Your directory from which spatch is called is processed next
o The directory provided with the --dir option is processed last, if used
