    fs: introduce inode operation ->update_time · c3b2da31
    Josef Bacik authored
    Btrfs has to make sure we have space to allocate new blocks in order to modify
    the inode, so updating time can fail.  We've gotten around this by having our
    own file_update_time but this is kind of a pain, and Christoph has indicated he
    would like to make xfs do something different with atime updates.  So introduce
    ->update_time, where we will deal with i_version an a/m/c time updates and
    indicate which changes need to be made.  The normal version just does what it
    has always done, updates the time and marks the inode dirty, and then
    filesystems can choose to do something different.
    
    I've gone through all of the users of file_update_time and made them check for
    errors with the exception of the fault code since it's complicated and I wasn't
    quite sure what to do there, also Jan is going to be pushing the file time
    updates into page_mkwrite for those who have it so that should satisfy btrfs and
    make it not a big deal to check the file_update_time() return code in the
    generic fault path. Thanks,
