  "message": "do CPU_DEAD migrating under read_lock(tasklist) instead of write_lock_irq(tasklist)\n\nCurrently move_task_off_dead_cpu() is called under\nwrite_lock_irq(tasklist).  This means it can\u0027t use task_lock() which is\nneeded to improve migrating to take task\u0027s -\u003ecpuset into account.\n\nChange the code to call move_task_off_dead_cpu() with irqs enabled, and\nchange migrate_live_tasks() to use read_lock(tasklist).\n\nThis all is a preparation for the futher changes proposed by Cliff Wickman, see\n\thttp://marc.info/?t\u003d117327786100003\n\nSigned-off-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nCc: Cliff Wickman \u003ccpw@sgi.com\u003e\nCc: Gautham R Shenoy \u003cego@in.ibm.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Srivatsa Vaddagiri \u003cvatsa@in.ibm.com\u003e\nCc: Akinobu Mita \u003cakinobu.mita@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
