    sysfs, kernfs: prepare mmap path for kernfs · fdbffaa4
    Tejun Heo authored
    We're in the process of separating out core sysfs functionality into
    kernfs which will deal with sysfs_dirents directly.  This patch
    rearranges mmap path so that the kernfs and sysfs parts are separate.
    sysfs_kf_bin_mmap() which handles the interaction with bin_attribute
    mmap method is factored out of sysfs_bin_mmap(), which is renamed to
    kernfs_file_mmap().  All vma ops are renamed accordingly.
    sysfs_bin_mmap() is updated such that it can be used for both file
    types.  This will eventually allow using the same file_operations for
    both file types, which is necessary to separate out kernfs.
    This patch doesn't introduce any behavior changes.
