Rick Macklem 0c695afb96 An intermittent problem with NFSv4 exporting of ZFS snapshots was ... reported to the freebsd-fs mailing list. I believe the problem was caused by the Readdir operation using VFS_VGET() for a snapshot file entry instead of VOP_LOOKUP(). This would not occur for NFSv3, since it will do a VFS_VGET() of "." which fails with ENOTSUPP at the beginning of the directory, whereas NFSv4 does not check "." or "..". This patch adds a call to VFS_VGET() for the directory being read to check for ENOTSUPP. I also observed that the mount_on_fileid and fsid attributes were not correct at the snapshot's auto mountpoints when looking at packet traces for the Readdir. This patch fixes the attributes by doing a check for different v_mount structure, even if the vnode v_mountedhere is not set.
