From b51d622ba8bdda20dd5d25f755d4fcf303478339 Mon Sep 17 00:00:00 2001 From: rmacklem Date: Sat, 23 May 2015 21:58:41 +0000 Subject: 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.
