Please clean this up, the code must reflect only the code upstream. No
config stuff like this should be used on the driver. I had to stop my
review here.
The CONFIG_ prefix shouldn't have been there as there is no Kconfig
option to select this.
Would like to just change it to a normal define without CONFIG_ prefix
instead?
This code is here to allow a limited version of the driver to run on
older kernels which do not have the necessary partial file read support.
By having it in the upstream codebase we don't need to maintain an
internal version of the driver. User can take the upstream kernel
module and compile it against an old version of the kernel by via the
define.
