is anyone using cephfs inline_data support?

A broad question for the cephfs user community: I've been looking at adding inline_data write support for kcephfs [1]. It's non-trivial to handle correctly in the kernel (due to the more complex locking, primarily), and I'm finding some bugs in what's already there. Is anyone actually enabling inline_data in their environments? Is this something we should be expending effort to support?
