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

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