| Hi,
| I have written a new function in linux/fs/read_write.c and I want to make
| the function avaliable to other kernel modules loaded using insmod.
| He is what I did:
| 1. Wrore the func my_func() in linux/fs/read_write.c
| 2. Used the macro EXPORT_SYMBOL(my_func) inside linux/fs/read_write.c
| 3. Have a signature of my_func in my_func.h
| 4. Include my_func.h in linux/fs/read_write.c and my_driver.c
| 5. Recompiled the kernel
| 6. Compiler my_driver as loadable module.
| 7. Brought my new kernel Up.
| 8 . Insmod my_driver.o
| Here I get the error "Unresolved symbol my_func"
| Can any one clarify this.
For what kernel version?
In 2.4.20, e.g., in linux/fs/Makefile, change the following line:
export-objs := filesystems.o open.o dcache.o buffer.o
to include read_write.o
