Subject: freevxfs: handle big endian HP-UX file systems
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

To support VxFS filesystems from HP-UX on x86 systems we need to
implement byte swapping, and to keep support for Unixware filesystems
it needs to be the complicated dual-endian kind ala sysvfs.

To do this properly we have to split the on disk and in-core inode
so that we can keep the in-core one in native endianness.  All other
structures are byteswapped on demand.
