Currently, when a work item is off-queue, work->data records the CPU it was last on, which is used to locate the last executing instance for non-reentrance, flushing, etc. We're in the process of removing global_cwq and making worker_pool the top level abstraction. This patch makes work->data point to the pool it was last associated with instead of CPU. After the previous WORK_OFFQ_POOL_CPU and worker_poo->id additions, the conversion is fairly straight-forward. WORK_OFFQ constants and functions are modified to record and read back pool ID instead. worker_pool_by_id() is added to allow looking up pool from ID. get_work_pool() replaces get_work_gcwq(), which is reimplemented using get_work_pool(). get_work_pool_id() replaces work_cpu(). This patch shouldn't introduce any observable behavior changes. Signed-off-by: Tejun Heo <tj@kernel.org> Reviewed-by: Lai Jiangshan <laijs@cn.fujitsu.com> |
