In fact, I did load it successfully in different kernel. What I worried
is that the
Module.symvers and System.map of these two kernel are different, and module
building needs them. I only fix some bugs of schedule code:
diff -uprN linux-2.6.32-431.el6.6.vsds.x86_64.orig/
linux-2.6.32-431.el6.6.vsds.x86_64/|diffstat -p0
linux-2.6.32-431.el6.6.vsds.x86_64/kernel/sched.c | 26 ++---
linux-2.6.32-431.el6.6.vsds.x86_64/kernel/sched_fair.c | 76
