On a loosely related topic to cifs inode handling ...
During the week of testing in Redmond earlier in the month, we had a
long discussion about the best way to handle caching/oplock.  It looks
like requesting "batch" oplock first (which allows you to defer
close operations) may be preferable, but doing this would require changing
the cifs destroy inode routine to send SMB close (would the vfs allow
the free inode routine to block?) and would allow us to use the same
network file handle for multiple opens in some case which would
greatly improve performance.
