/* * Update the access, modified, and inode change times as specified by the * IACCESS, IUPDATE, and ICHANGE flags respectively. The IMODIFIED flag is * used to specify that the inode needs to be updated but that the times have * already been set. The access and modified times are taken from the second * and third parameters; the inode change time is always taken from the current * time. If UPDATE_WAIT or UPDATE_DIROP is set, then wait for the disk * write of the inode to complete. */
