snapshots directories in the
archives, and should be applied using the patch(1)
utility to the source code of the release they are derived from. For
example, to get the full source code to snapshot
2.6.1-rc1-git5, get and extract the
linux-2.6.0.tar.bz2 archive, then use the patch
utility to apply patch-2.6.1-rc1.bz2 followed by
patch-2.6.1-rc1-git5.bz2.
If you find a bug in a snapshot release, please see Reporting Linux Kernel Bugs on the front page.
Most of the developer trees are also directly available using the git software. See http://www.kernel.org/git/ for a list of git repositories available on kernel.org.
