Subject[PATCH 0/5] percpu_ida+Co: Make percpu_ida_alloc accept task state bitmask
Date
From: Nicholas Bellinger <nab@linux-iscsi.org>

Hello Linus,

Here is the series for converting percpu_ida_alloc() + consumer
usage to accept the task state bitmask parameter, w/o the extra
legacy gfp_t wrapper.

Also, given that the first three patches needs to be backported
to different kernel versions, the series has been broken up into
seperate commits for blk-mq (v3.13.y) and target/* (v3.12.y) with
the minimal set of changes marked for stable.

The last two patches propigate task state bitmask usage further
up the blk-mq + target/iscsi stack, and as improvements are not
marked for stable code.

CC'ing Ingo + Peter for TASK_RUNNING + prepare_to_wait() bit.

Thank you,

--nab
