https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D253428 --- Comment #3 from Rick Macklem <rmacklem@FreeBSD.org> --- Ok. I think the best change would be to note that d_off =3D=3D 0 can be generated by certain file systems. such as NFS. I think a value of 0 for d_off is always meaningless and should be ignored. An offset =3D=3D 0 refers to beginning of directory and would never refer to a valid "next entry", I think? Feel free to update the man page, or I may get around to it someday. Now that I'm done with NFS over TLS, I am going to start to work on directory delegations. For the case of servers that present monotonically increasing offset cookies, more might be doable here. --> I plan on proposing an extension to NFSv4.2 which is a new attribute to indicate monotonically increasing directory offset cookies, because that is the only case where the NFS client can implement directory delegations. --> These allow a directory cache to be updated via callbacks with add/remove entry info. from a server. No one has implemented these, but they might be useful. --=20 You are receiving this mail because: You are the assignee for the bug.=
