rpurdie pushed a commit to branch master-next
in repository bitbake.
commit 20c0da434f141cc6934b5d567fed1b99013bf051
Author: Christopher Larson <chris_larson at mentor.com>
AuthorDate: Sat Apr 30 12:52:49 2016 -0700
Provide LAYERDIR_RE for layer.conf
This variable is a regex-escaped version of LAYERDIR, for safer use in
BBFILE_PATTERN, so as to avoid issues with regex special characters in the
layer path.
