Hi Ratheendran,

I have attached the patch I used for building under linux 3.4.7 -- I got similar
build errors as you, so hopefully it will help.

I also have a patch to fix the 'inband tags' option on linux, but I am waiting
for feedback (see previous mail) before releasing.

Cheers,

Angus

Subject: [PATCH (linux-stm)] yaffs: fix build errors for linux 3.4.7

This patch fixes some yafss errors when building under linux 3.4.7 (probably due
to kernel API changes).
