17 * In a seqid-mutating op, this macro controls which error return
18 * values trigger incrementation of the seqid.
19 *
20 * from rfc 3010:
21 * The client MUST monotonically increment the sequence number for the
22 * CLOSE, LOCK, LOCKU, OPEN, OPEN_CONFIRM, and OPEN_DOWNGRADE
23 * operations. This is true even in the event that the previous
24 * operation that used the sequence number received an error. The only
25 * exception to this rule is if the previous operation received one of
26 * the following errors: NFSERR_STALE_CLIENTID, NFSERR_STALE_STATEID,
27 * NFSERR_BAD_STATEID, NFSERR_BAD_SEQID, NFSERR_BADXDR,
28 * NFSERR_RESOURCE, NFSERR_NOFILEHANDLE.
