Modified Files: src/sys/miscfs/genfs: genfs_io.c Log Message: in genfs_getpages(), mark the vnode dirty (ie. add to syncer worklist and set VI_WRMAPDIRTY) after we have busied the pages rather than before. this prevents other threads calling genfs_do_putpages() from marking the vnode clean again while we're in the process of creating new writable mappings, since such threads will wait for the page(s) to become unbusy before proceeding. fixes the problem recently reported by hannken@ on tech-kern.
