Tejun Heo 2bc00aef03 writeback: consolidate dirty throttle parameters into dirty_throttle_control ... Dirty throttling implemented in balance_dirty_pages() and its subroutines makes use of a number of parameters which are passed around individually. This renders these functions somewhat unwieldy and makes it difficult to add or change the involved parameters. Also some functions use different or conflicting naming schemes for the same parameters making the code confusing to follow. This patch consolidates the main parameters into struct dirty_throttle_control so that they can be passed around easily and adding new paramters isn't painful. This also unifies how a given parameter is named and accessed. The drawback of using this type of control structure rather than explicit paramters is that it isn't immediately obvious which function accesses and modifies what; however, it's fairly clear that the benefits outweigh in this case. GDTC_INIT() macro is provided to ease initializing dirty_throttle_control for the global_wb_domain and balance_dirty_pages() uses a separate pointer to point to its global dirty_throttle_control. This is to make it uniform with memcg domain handling which will be added later. This patch doesn't introduce any behavioral changes.
