In that level no io_priority_class-es exist. Instead, all the IO happens in the context of current sched-group. File API no longer accepts prio class argument (and makes io_intent arg mandatory to impls). So the change consists of - removing all usage of io_priority_class - patching file_impl's inheritants to updated API - priority manager goes away altogether - IO bandwidth update is performed on respective sched group - tune-up scylla-gdb.py io_queues command The first change is huge and was made semi-autimatically by: - grep io_priority_class | default_priority_class - remove all calls, found methods' args and class' fields Patching file_impl-s is smaller, but also mechanical: - replace io_priority_class& argument with io_intent* one - pass intent to lower file (if applicatble) Dropping the priority manager is: - git-rm .cc and .hh - sed out all the #include-s - fix configure.py and cmakefile The scylla-gdb.py update is a bit hairry -- it needs to use task queues list for IO classes names and shares, but to detect it should it checks for the "commitlog" group is present.
