Subject: [PATCH v2 1/2] kselftest: add capability to skip chosen TARGETS
Date: Thu, 26 Sep 2019 18:52:18 +0100	[thread overview]
Message-ID: <> (raw)
In-Reply-To: <>

Let the user specify an optional TARGETS skiplist through the new optional
SKIP_TARGETS Makefile variable.

It is easier to skip at will using a reduced and well defined list of
possibly problematic targets with SKIP_TARGETS than to provide a partially
stripped down list of good targets using the usual TARGETS variable.

Signed-off-by: Cristian Marussi <>
v1 --> v2
- fixed commit msg
- added documentation fix
- added forced override to allow TARGETS= and SKIP_TARGETS
  being both passed on the cmdline
