Subject: getcwd() returning -ENOENT???

Hi,

Can someone explain why I'm seeing the following on test12-pre7:

bash# /bin/pwd
/bin/pwd: cannot get current directory: No such file or directory
bash# vdir /proc/self/.
...
lrwxrwxrwx 1 root root 0 Dec 7 14:52 cwd -> /net/raistlin/raistlin-v2.4/linux-ebsa285 (deleted)
...
lrwxrwxrwx 1 root root 0 Dec 7 14:52 root -> /
...
bash# vdir
... <complete listing of directory> ...
bash# cat /proc/mounts
/dev/root / ext2 rw,noatime 0 0
/proc /proc proc rw 0 0
/dev/hda3 /var ext2 rw,nodiratime 0 0
/dev/hda5 /usr ext2 rw,noatime 0 0
/dev/hda6 /home ext2 rw 0 0
none /dev/pts devpts rw 0 0
none /dev/shm shm rw 0 0
automount(pid482) /net/flint autofs rw 0 0
automount(pid499) /net/raistlin autofs rw 0 0
raistlin:/usr/src/v2.4 /net/raistlin/raistlin-v2.4 nfs rw,v2,rsize=4096,wsize=4096,hard,udp,lock,addr=raistlin 0 0

Rebooting the machine and trying again caused this weirdness to disappear.

First time around, the network wasn't initially available when autofs
started.

Directory is unhashed. Normally it means that sucker had been deleted.

Ditto.

Which means that it is _not_ deleted. Looks like it had been invalidated
for some reason. Try to reproduce that on -test10 - that should be before
NFS changes.
