John Baldwin dd688800e1 Add a custom VOP_PATHCONF method for fdescfs. ... The method handles NAME_MAX and LINK_MAX explicitly. For all other pathconf variables, the method passes the request down to the underlying file descriptor. This requires splitting a kern_fpathconf() syscallsubr routine out of sys_fpathconf(). Also, to avoid lock order reversals with vnode locks, the fdescfs vnode is unlocked around the call to kern_fpathconf(), but with the usecount of the vnode bumped.
