So ... it means that this list is not the right place and I should go
to the kernel sources to find this module??

I tried to download
http://git.infradead.org/linux-mtd.git/blob_plain/HEAD:/drivers/mtd/nand/nandsim.c
 and used
This Makefile (http://www.cyberciti.biz/tips/compiling-linux-kernel-module.html):
obj-m = nandsim.o
KVERSION = $(shell uname -r)
all:
make -C /lib/modules/$(KVERSION)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(KVERSION)/build M=$(PWD) clean

make -C /lib/modules/3.17.3-200.fc20.x86_64/build
M=/home/bruno/dev/mtd-utils/reb modules
make[1]: Entering directory `/usr/src/kernels/3.17.3-200.fc20.x86_64'
  CC [M]  /home/bruno/dev/mtd-utils/reb/nandsim.o
  Building modules, stage 2.
  MODPOST 1 modules
WARNING: "nand_release" [/home/bruno/dev/mtd-utils/reb/nandsim.ko] undefined!

  LD [M]  /home/bruno/dev/mtd-utils/reb/nandsim.ko
make[1]: Leaving directory `/usr/src/kernels/3.17.3-200.fc20.x86_64'


But then:
sudo insmod nandsim.ko first_id_byte=0x20 second_id_byte=0x33
insmod: ERROR: could not insert module nandsim.ko: Unknown symbol in module

I am stuck here.
