I was looking for some help/instructions on how to build a kernel module from source. I am running RHEL-5.1 kernel 2.6.18-53.el5 x86_64 and trying to build the xfs module. I tried finding the xfs module but am having trouble. Building it from source appears to be my only other option.

Well a first step would be to ensure that you have the kernel source for the kernel you are currently running available. Then, depending on what the module source you have specifies in its howto / building documentation you'll need to untar / unbzip the source in a directory, then go into that directory in a terminal and do something similar to this:

./configure --with-kernel-source=/usr/src/linux (or wherever your kernel sources are located)

make

make install

Then you might additionally need to do something like

modprobe <modulename>

to actually load the module once it has been compiled.
