DESCRIPTION

16       Update the mtime and ctime members of an inode and mark the inode for
17       writeback. Note that this function is meant exclusively for usage in
18       the file write path of filesystems, and filesystems may choose to
19       explicitly ignore update via this function with the S_NOCMTIME inode
20       flag, e.g. for network filesystem where these timestamps are handled by
21       the server.
