Great, lLooks quite good :) Updated my port from pre4 to rc1 [1] to check
for differences.
Most of the differences are due to the *_mm_counter macros, which I
modified to call the Linux-VServer accounting stuff. And some whitespace
noise (from both of us I guess, didn't check, but I know that I cause some
every now and then ;).

Well, I also left it out, as the NFS_MOUNT_BROKEN_SUID stuff is gone in
2.6.12-rc4 ;)

The handling of mount flags was moved around a bit, nfs_sb_init() is the
place where it happens now...

There are two or three other small issues, IIRC QUOTA_CTL and rss
accounting, a diff between the ports tells you more ;)

Hehe :)
I wondered about that change you did in get_tid_list:
- tids[nr_tids] = vx_map_pid(tid);
- nr_tids++;
+ tids[nr_tids++] = vx_map_pid(tid);
It looks quite good I'd say, was that a known bug in 2.6.12-rc4?
Anyways, good job! Having different people (not too many ;) doing ports
can help to find flaws. (And of course Bertl doesn't have to do all the
work then ;)
