[Intel-gfx] [PATCH i-g-t 3/3] Remove gem_concurrent_all, since it is now superfluous
David Weinehall
david.weinehall at linux.intel.com
Fri Oct 23 04:42:36 PDT 2015
With the addition of unified command-line handling for
slow/combinatorial tests we no longer need the
gem_concurrent_blit/gem_concurrent_all magic. Delete the latter,
since the former has a more descriptive file name.
