fs: Add new VFCF_xxx flags for va_filerev
Richard Kojedzinszky <rich...@kojedz.in> reported a problem via
email, where the Linux NFSv4.2 client did not detect a change in a
directory on a FreeBSD NFSv4.2 server.
Adding support for the NFSv4.2 change_attr_type attribute seems
to have fixed the problem. This requires that the server file system
indicate if it increments va_filerev by one, since that file attribute
is used for the NFSv4.2 change attribute. Fuse requires an indication
that va_filerev is based on ctime.
This patch adds VFCF_FILEREVINC and VFCF_FILEREVCT to indicate this.
A future patch to the NFS server will use these flags.
