Where does a vnode gets dirty?

[manu%netbsd.org@localhost (Emmanuel Dreyfus)]

Hello

When copying data to a vnode using ubc_alloc() ubc_uiomove() and
ubc_release(), where does the kernel notes that data is dirty and will
need to be written by VOP_PUTPAGE? Is it the responsability of the
caller to request it (how?), or is it done somewhere in UBC?
