See README.txt for information on primary utrace development. I am also maintaining a set of patches relative to certain stable 2.6.x kernels, using quilt. Each backport patch seris will tend to lag behind the main development a bit. All utrace changes are made inn the current version first and then backported. I update the backports as needed for builds. Each series file has comments giving the GIT revision ids of the 2.6-current/ patches to which the backport corresponds. As of 2007-12-14 there are these backport versions here: 2.6.23 (relative to 2.6.23.10) used for Fedora 7 and 8 update kernels 2.6.18 used for RHEL5 update kernels These backports are no longer up to date: 2.6.22 2.6.21 2.6.20.11
