inode_operations create not called
I'm trying to write a little kernel module that takes care of a variation of the FAT file system.
So far I have set up things accordingly: the fill_super function and a bunch of callback functions such as readdir and directory lookup and file read functions. All of these work ok. I can mount an image file and can look up the root dir and read files in it.
However, when I try to make a new file in it, it seems like the create function in the inode_operations gets never called. It's the function that is supposed to take care of creating a new file. I acutally googled in search of someone with the same problem but all I got was stuff saying that the Linux kernel calls the create function in inode_operations when trying to create a new file.
Simply put the lookup function in inode_opeations gets called OK but the create function has been ignored. So I have no idea what's happening.
Anyone with experience with implementing your own file system, could you help me?

Without code, not much we can do...Sometimes, real fast is almost as good as real time.

Just some random thoughts, how are you creating the new file? Is that using "creat" or "open" sys.call to create a new file.?
As Rubberman,without code we can guess few things - but not exact answer.
