I've uploaded a new device-mapper tarball corresponding to this:


The tarball contains up-to-date combined patches for 2.4.20,
incorporating a few minor bug fixes and a little restructuring.
(NB The 2.4.19 patches in the tarball have *not* been updated.)

The userspace library has been updated to prepare for a device-mapper
API fix planned for the next release.

  The fix is to a few field definitions in the dm_ioctl structure and
  the change itself is not backwards-compatible.  But, as of this release,
  if the userspace library is *compiled against* a kernel tree that uses
  the *new* dm_ioctl definition, then the library will, if necessary,
  automatically fall back at *runtime* to using the old definition.
  In other words, provided this libdevmapper is compiled against the
  new definition, kernels/modules using the different definitions can 
  be interchanged without having to interchange libdevmapper.so.
  'configure --disable-compat' turns off this behaviour.
