/*
* the nfs v3 file handle structure definitions are _almost_ the same
* on linux and solaris. the key difference are:
*
* 1) on linux fh3_length is an unsigned short where as on solaris it's
* an int.
*
* 2) on linux the file handle data doesn't 32 bit members, so the structure
* is not 32 bit aligned. (where as on solaris it is.)
*
* so rather than defining a structure that would allow us to intrepret
* all the contents of the nfs v3 file handle here, we decide to treate
* the file handle as an array of chars. this works just fine since it
* avoids the alignment issues and the actual file handle handle contects
* are defined by the nfs specification so they are common across solaris
* and linux. we do the same thing for nfs v2 file handles.
