From 5339bdad96ace2fa76bf5d80b8596ad84b037aed Mon Sep 17 00:00:00 2001 From: Karthik Nayak Date: Wed, 17 Feb 2016 23:36:17 +0530 Subject: ref-filter: introduce remote_ref_atom_parser() Introduce remote_ref_atom_parser() which will parse the '%(upstream)' and '%(push)' atoms and store information into the 'used_atom' structure based on the modifiers used along with the corresponding atom.
