Probably best as a BoF:
Based on feedback from the v3 RFC it would seem we *may* be on the final stretch
from s/RFC/PATCH in removing the kthread freezer APIs from filesystems [0]. To
be clear that's not to say this is done, but just that it seems we have
some agreement towards what to do and this just needs to get baked now,
and the last part -- obviously tested.
Kthread freezing was added to *help* with the lack of the VFS layer dealing with
freezing / thawing for us. But if you look, a few subsystems make use of the
kthread freezer API now. So after we complete removal on the filesystems side of
things, does anyone see issues with just doing similar removal from other
subsystems? Or has the kthread freezer API now been embraced for other reasons
other than the original one?
