[PATCH i-g-t 3/3] Remove gem_concurrent_all, since it is now superfluous

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
