writeback: initialize global_dirty_limit This prevents global_dirty_limit from remaining 0 (the initial value) for long time, since it's only updated in update_dirty_limit() when above the dirty freerun area. It will avoid unexpected consequences when some random code use it as a convenient approximation of the global dirty threshold. Signed-off-by: Fengguang Wu <fengguang.wu@intel.com>
