591 * hfs_notify_change()
593 * Based very closely on fs/msdos/inode.c by Werner Almesberger
595 * This is the notify_change() field in the super_operations structure
596 * for HFS file systems. The purpose is to take that changes made to
597 * an inode and apply then in a filesystem-dependent manner. In this
598 * case the process has a few of tasks to do:
599 * 1) prevent changes to the i_uid and i_gid fields.
600 * 2) map file permissions to the closest allowable permissions
601 * 3) Since multiple Linux files can share the same on-disk inode under
602 * HFS (for instance the data and resource forks of a file) a change
603 * to permissions must be applied to all other in-core inodes which
604 * correspond to the same HFS file.
