yangerkun 2285e1496d dm-crypt: export sysfs of all workqueues ... Once there is a heavy IO load, so many encrypt/decrypt work will occupy all of the cpu, which may lead to the poor performance for other service. So the improved visibility and controls over dm-crypt workqueues, as was offered with commit a2b8b2d975 ("dm crypt: export sysfs of kcryptd workqueue"), seems necessary. By exporting dm-crypt's workqueues in sysfs, the entry like cpumask/max_active and so on can help us to limit the CPU usage for encrypt/decrypt work. However, commit a2b8b2d975 did not consider that DM table reload will call .ctr before .dtr, so the reload for dm-crypt failed because the same sysfs name was present. This was the original need for commit 48b0777cd9 ("Revert "dm crypt: export sysfs of kcryptd workqueue""). Reintroduce the use of WQ_SYSFS, and use it for both the IO and crypt workqueues, but make the workqueue names include a unique id (via ida) to allow both old and new sysfs entries to coexist.
