45 * Prior to linux-2.6.33 only O_DSYNC semantics were implemented and
46 * they used the O_SYNC flag. As of linux-2.6.33 the this behavior
47 * was properly split in to O_SYNC and O_DSYNC respectively.

56 * The vnode AT_ flags are mapped to the Linux ATTR_* flags.
57 * This allows them to be used safely with an iattr structure.
58 * The AT_XVATTR flag has been added and mapped to the upper
59 * bit range to avoid conflicting with the standard Linux set.
