Author: rmacklem Date: Sat Jun 6 20:54:41 2015 New Revision: 284101 URL: https://svnweb.freebsd.org/changeset/base/284101 Log: MFC: r283330 The NFS client generated directory block(s) with d_fileno == 0 so that it would not return less data than requested. Since returning less directory data than requested is not a problem for FreeBSD and even UFS no longer returns directory structures with d_fileno == 0, this patch stops the client from doing this. Although entries with d_fileno == 0 should not be a problem, the man pages no longer document that these entries should be ignored, so there was a concern that these entries might be an issue in the future.
