Subject: Sync with Linux 2.4.0-test11-pre5 Provide backward compatibility
 tested     against 2.2.18pre21 As usual, since all 2.4.0-test* kernels set
 LINUX_VERSION_CODE to the same     value, if you are running a 2.4.0-test
 kernel, you MUST be running     2.4.0-test11-pre4 or later (although anything
 after 2.4.0-test11-pre1     should work fine -- I tested with pre4/pre5). I
 expect 2.2.x support to     continue to work for all recent kernels, but I
 tested with 2.2.18pre21     -- we use the old intermodule symbol
 communication for 2.2.x kernels,     so they should all continue to work.
