85d0052723 workaround for UBC limit. 
while our nfsd announces MAXBSIZE as wtmax for tcp,
VOP_GETPAGES of filesystems that uses genfs_getpages can't
handle >= MAX_READ_AHEAD(16) pages at once.
therefore, depending on PAGE_SIZE of the machine and file offset of
a read request, we can't VOP_GETPAGES the range at once.

a340c1b544 when a result of NFSv3 READLINK is too long for us, 
return ENAMETOOLONG rather than EBADRPC.
(it's our implementation limit, not protocol limit.)

9e95dcb696 Change some subordinate functions to take a "struct nfsnode" argument 
instead of "struct vnode". This saves a number of pointer dereferences;
it sums up to about half a kB for me. And it paves the way for future
fixes.
While cleaning up, eliminate a write-only member of "struct nfsreq"
and a pointless assignment in the NFS_V2_ONLY case.

80ecd573c0 PR/1796: John Kohl: statfs misbehaves under chrooted environments. 
- Under chroot it displays only the visible filesystems with appropriate paths.
- The statfs f_mntonname gets adjusted to contain the real path from root.
- While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(),
  and factored out some of the vfsop statfs() code to copy_statfs_info(). This
  fixes the problem where some filesystems forgot to set fsid.
- Made coda look more like a normal fs.

043759a005 - do FILESYNC writes if we're freeing the page or the page doesn't 
belong to us.  otherwise, data will be lost on server crash.
- use b_bcount instead of b_bufsize to determine
  how many pages we should deal with.

based on a patch from Chuck Silvers.
