------- Comment From dougm...@us.ibm.com 2018-04-23 16:14 EDT------- Regarding the "init" condition of the work item in the crash analysis, besides INIT_WORK() this condition would also be present after using list_del_init(), which is done just prior to executing the work function. So, if multiple pools were pointing to this work item, when one (any, all) starts to execute it then this condition will exist. This state should show the work item removed from the pool, although it is only possible for that remove to work for one pool (the last one to which the entry was added), and any other pools will not be able to get rid of that work item. The exact result of all this is still not clear, but it seems there are several possible ways that the tasks get effectively hung.
