This directory tree contains the supporting userspace files (libdevmapper and dmsetup) you need when working with device-mapper. The patches subdirectory also includes up-to-date device-mapper kernel patches for 2.4.26-rc1 and old patches for 2.4.20, 2.4.21 and 2.4.22 onwards. 2.6 kernels already contain the device-mapper core, but (as at March 2004) you need to apply development patches if you want snapshot and pvmove functionality. For more information about device-mapper please read the INTRO file. Installation instructions are in INSTALL.
