Since moving to memalloc_nofs_save/restore, SUNRPC has stopped setting the
GFP_NOIO flag on sk_allocation which the networking system uses to decide
when it is safe to use current->task_frag.

Um, what's task_frag?

Its a per-task page_frag used to coalesce small writes for networking -- see:

I am not seeing this in the mainline. Where can find this commit?

Okay. I see this commit in the mainline. However, I don't see the
sk_use_task_frag in mainline.

thanks,
