2010-05-17 10:40:06 +00:00
Joel Brobecker 070abf125e Add reset_schedlock declaration in target.h.
This patches improves a couple of previous patches:
  - one that introduces reset_schedlock, but failed to add a declarationl;
  - one that was checked in to avoid a compilation failure due to that
    missing declaration.
It also improves the declaration itself to better conform to our coding
practices.  Same for the comments.
