From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx> Hi Linus, Here is the -v2 series for converting percpu_ida_alloc() + consumer usage to accept the task state bitmask parameter, w/o the extra legacy gfp_t wrapper. As requested, the first patch contains only the parameter change to percpu_ida_alloc() + existing consumers, and makes no semantic or behavior change. This patch is CC'ed for stable, and will need some light massaging to apply back to v3.12.y. The second patch is a blk-mq cleanup to propigate the task state bitmask usage up to the blk-mq vs. legacy split in blk_get_request(). The last patch fixes the original iscsi-target session reset bug by passing TASK_INTERRUPTIBLE, and adds the signal_pending_state() bit required in percpu_ida_alloc() code. This is also CC'ed for v3.12.y. CC'ing Ingo + Peter for TASK_RUNNING + prepare_to_wait() bit.
