Lock the vnode around the call to VOP_GETATTR. Move the locked code and vn_fullpath (that call malloc(..., M_WAITOK)) from under the vm object lock, since sleep is not allowed while holding the mutex. Being there, wrap VOP_GETATTR call with conditional Giant aquire. Currently this is (almost) noop because pseudofs is Giant-locked. Approved by: pjd (mentor)
