Hi all, what I want is to incorporate one extra field of information in the inode structure. Can anybody tell me where I will find the definition of inode so that I can add the extra field.What will be the other causes of concern, and what more functions accessing the inodes will I need to change? Thanks in advance. I looked under fs in the kernel source, found inode.c requires some updation(If anyone please point out what functions should I change there -it would still help me immensely).But what I was unable to find is the inode definition.Please help me. Thanks for any help that you can give .
