Lustre seemed to encounter the same oops and fixed it in a different way, removing
set_page_writeback() altogether:
https://lkml.org/lkml/2015/7/30/806

We cannot just remove the call to set_page_writeback() at least because later
we wait on PG_Writeback flag of that page (in jwait_io())... What is meant by
"synchronous write" in that Lustre patch? Is our write "synchronous" in the
same sense? I don't know VFS well. Cc'ing Oleg.
