Note that unlike fs_reclaim_acquire/release gfpflags_allow_blocking does not consult the PF_MEMALLOC flags. But there is no flag equivalent for GFP_NOWAIT, hence this check can't go wrong due to memalloc_no*_save/restore contexts.

I have a patch series that adds memalloc_nowait_save/restore.

tbh this was a typoed git send-email, but thanks for the heads-up, I'll adjust the patch accordingly.

Cheers, Daniel
