Sorry to be a continued bringer of bad news.
During the course of applying patch-2.1.63 to an NFS-mounted tree (and
cleaning up a large number of *.orig files afterwards), linux/include
disappeared. I resurrected it by forcibly umount-ing the server as root
and letting the automounter re-grab it. Bingo! Everything fine.
This was the only log entry:
Nov 13 21:15:32 amd kernel: d_alloc: 889 unused, pruning dcache
Nov 13 21:15:33 amd last message repeated 13 times
Nov 13 21:17:10 amd kernel: nfs_revalidate_inode: getattr failed, error=-2
Nov 13 21:17:47 amd last message repeated 4 times
Server and client were using 2.1.62 (baseline, save for Cyrix patch). The
server ran unfsd. This is my standard test setup that managed to trigger
numerous bugs in the past.
