Why these super-early line breaks in the committ message?  They make
the text much more awkware compared to say:

This patch converts bioset_create() and bioset_create_nobvec() to not
create a workqueue so alloctions will never trigger
punt_bios_to_rescuer(). It also introduces bioset_create_rescued() and
bioset_create_nobvec_rescued() which preserve the old behaviour.

I'd much prefer a single new bioset_create with a bunch of flags
arguments over the number of new functions and these bool arguments.
