Hi Kunal,

Have a look at this which explains your question --

The kernel apis change might change from each version.

To keep a tap on them for your driver or the driver you are following, keep
looking at the changelogs that comes with each new kernel release version -

Hi, I am new to kernel coding and right now trying to implement address
space operations on top of WrapFS. I noticed that the
address_space_operations declaration has a field write_begin where I was
expecting prepare_write. Is it just a change of name with newer versions of
kernel or is there some significant change that has been made to it ?

Thanks
