------- Comment #8 from sfrench at us.ibm.com  2009-12-02 15:38 CST -------
One difficulty with special casing ext2/ext3 (e.g. checking fstype in SMB tconx
response) is that the root of the share could be ext3 but directories
underneath that could be ext4 or xfs (for example) which would allow accurate
timestamps.  We can (eventually) detect when we pass from one volume to another
(on the server) in traversing a directory hierarchy by looking at the fsid in
the QueryPathInfo and QueryFileInfo responses (and e.g. could do "implicit
mounts" when we cross a volume boundary to make it easier to cache these volume
properties for each server volume we encounter) - we may eventually need to do
that to handle duplicate inode numbers for volumes mounted under one another on
a share.
