They did it\nby first iterating pools and then visiting all pwqs (pool_workqueues)\nof all workqueues and process it if its pwq-\u003epool matches the current\npool.  This is rather backwards and done this way partly because\nworkqueue didn\u0027t have fitting iteration helpers and partly to avoid\nthe number of lock operations on pool-\u003elock.\n\nWorkqueue now has fitting iterators and the locking operation overhead\nisn\u0027t anything to worry about - those locks are unlikely to be\ncontended and the same CPU visiting the same set of locks multiple\ntimes isn\u0027t expensive.\n\nRestructure the three functions such that the flow better matches the\nlogical steps and pwq iteration is done using for_each_pwq() inside\nworkqueue iteration.\n\n* freeze_workqueues_begin(): Setting of FREEZING is moved into a\n  separate for_each_pool() iteration.  pwq iteration for clearing\n  max_active is updated as described above.\n\n* freeze_workqueues_busy(): pwq iteration updated as described above.\n\n* thaw_workqueues(): The single for_each_wq_cpu() iteration is broken\n  into three discrete steps - clearing FREEZING, restoring max_active,\n  and kicking workers.  The first and last steps use for_each_pool()\n  and the second step uses pwq iteration described above.\n\nThis makes the code easier to understand and removes the use of\nfor_each_wq_cpu() for walking pwqs, which can\u0027t support multiple\nunbound pwqs which will be needed to implement unbound workqueues with\ncustom attributes.\n\nThis patch doesn\u0027t introduce any visible behavior changes.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReviewed-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\n"
