Christoph Hellvig NAKed the series. If you are interested in pursuing this particular commit, let me suggest:

Add an unsigned int pf_malloc_mask to struct workqueue_struct and copy the PF_MEMALLOC* bits from currect->flags into it in alloc_workqueue(). In process_one_work(), we do an memalloc_flags_{save,restore} using pf_malloc_mask.

I do not see any need for translating the PF_MALLOC* bits into gfp_t and back again.
