Hi,

With linux kernel version 4.10.0-38-generic, when I compile yaffs2 as an out of tree module, I get the following warning:

WARNING: "readlink_copy" [/home/abjoshi/workspace/cse523/yaffs2/yaffs2multi.ko] undefined!

I did a bit of digging and found that 'readlink_copy' is used in yaffs_readlink when the kernel version is greater than 3.15 and is in fact, not exported which explains the warning, I think.

I believe I am missing something here, module obviously cannot have undefined symbols. Is this a kernel version problem? Any help is greatly appreciated.

My compilation steps:

 - git clone

 - make

--

Thanks and Regards,

Abhishek Joshi
