[PATCH] Turn do_sync_file_range() into do_sync_mapping_range()
do_sync_file_range() accepts a file * from which it takes an address_space to sync. Abstract out the bulk of the function into do_sync_mapping_range() which takes the address_space directly. This way callers who want to sync an address_space directly can take advantage of the functionality provided. do_sync_file_range() is preserved as a small wrapper around do_sync_mapping_range(). Ocfs2 in particular would like to use this to initiate a sync of a specific inode range during truncate, where a file * may not be available.
