Description

Building Lustre server modules for ubuntu 24.04 were successful, but when built modules were loaded, it failed due to the following errors.

modprobe libcfs
modprobe: ERROR: could not insert 'libcfs': Exec format error

[ 4159.185743] module libcfs: .gnu.linkonce.this_module section size must match the kernel's built struct module size at run time

I followed steps https://wiki.whamcloud.com/display/PUB/Build+Lustre+MASTER+with+Ldiskfs+on+Ubuntu+20.04.1+from+Git to build lustre modules/binaries.
Although it's a bit old information (for ubuntu 20.04), most of steps still worked for ubuntu24.04.

Also, two patches are still needed for ubuntu 24.04 server build against master.
