Hi Pavel,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on next-20200622]
[cannot apply to linus/master v5.8-rc2 v5.8-rc1 v5.7 v5.8-rc3]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use as
req->iopoll() is not necessarily called by a task that submitted a
request. Because of that, it's dangerous to grab_env() and punt async
on -EGAIN, potentially grabbinf another task's mm and corrupting its
memory.
Do resubmit from the submitter task context.
