I'm trying to understand the page cache mechanism, but I have a doubt and couldn't find any documentation about it, neighter was able to understand reading the code. Hope that someone can help me and/or indicate some doc.
Every inode has an address_space, that keeps a list of cached pages in a digital tree. So far so good. Now the doubt: the inode struct has two address_spaces, i_mapping and i_data. As far as I could understand, i_mapping is the address_space I'm looking for, since it is passed to the readpage method, but what is i_data function?
TIA, Luciano Stertz
