Is the description of each probe available somewhere? How do I figure out which argument has what value using this information from 'dtrace -lvP vminfo', for example? 19018 vminfo mach_kernel vnode_pagein pgpgin pager_return_t vnode_pagein() in xnu-1456.1.26/bsd/vm/vnode_pager.c has this bit Which probe can tell me the address of the pages that are being paged in, though?
