- * Flags to dlm_lock
- *
- * DLM_LKF_NOQUEUE
- *
- * Do not queue the lock request on the wait queue if it cannot be granted
- * immediately.  If the lock cannot be granted because of this flag, DLM will
- * either return -EAGAIN from the dlm_lock call or will return 0 from
- * dlm_lock and -EAGAIN in the lock status block when the AST is executed.
- *
- * DLM_LKF_CANCEL
- *
- * Used to cancel a pending lock request or conversion.  A converting lock is
- * returned to its previously granted mode.
- *
- * DLM_LKF_CONVERT
- *
- * Indicates a lock conversion request.  For conversions the name and namelen
- * are ignored and the lock ID in the LKSB is used to identify the lock.
- *
- * DLM_LKF_VALBLK
- *
- * Requests DLM to return the current contents of the lock value block in the
- * lock status block.  When this flag is set in a lock conversion from PW or EX
- * modes, DLM assigns the value specified in the lock status block to the lock
- * value block of the lock resource.  The LVB is a DLM_LVB_LEN size array
- * containing application-specific information.
- *
- * DLM_LKF_QUECVT
- *
- * Force a conversion request to be queued, even if it is compatible with
- * the granted modes of other locks on the same resource.
- *
- * DLM_LKF_IVVALBLK
- *
- * Invalidate the lock value block.
- *
- * DLM_LKF_CONVDEADLK
- *
- * Allows the dlm to resolve conversion deadlocks internally by demoting the
- * granted mode of a converting lock to NL.  The DLM_SBF_DEMOTED flag is
- * returned for a conversion that's been effected by this.
- *
- * DLM_LKF_PERSISTENT
- *
- * Only relevant to locks originating in userspace.  A persistent lock will not
- * be removed if the process holding the lock exits.
- *
- * DLM_LKF_NODLCKWT
- *
- * Do not cancel the lock if it gets into conversion deadlock.
- * Exclude this lock from being monitored due to DLM_LSFL_TIMEWARN.
- *
- * DLM_LKF_NODLCKBLK
- *
- * net yet implemented
- *
- * DLM_LKF_EXPEDITE
- *
- * Used only with new requests for NL mode locks.  Tells the lock manager
- * to grant the lock, ignoring other locks in convert and wait queues.
- *
- * DLM_LKF_NOQUEUEBAST
- *
- * Send blocking AST's before returning -EAGAIN to the caller.  It is only
- * used along with the NOQUEUE flag.  Blocking AST's are not sent for failed
- * NOQUEUE requests otherwise.
- *
- * DLM_LKF_HEADQUE
- *
- * Add a lock to the head of the convert or wait queue rather than the tail.
- *
- * DLM_LKF_NOORDER
- *
- * Disregard the standard grant order rules and grant a lock as soon as it
- * is compatible with other granted locks.
- *
- * DLM_LKF_ORPHAN
- *
- * not yet implemented
- *
- * DLM_LKF_ALTPR
- *
- * If the requested mode cannot be granted immediately, try to grant the lock
- * in PR mode instead.  If this alternate mode is granted instead of the
- * requested mode, DLM_SBF_ALTMODE is returned in the lksb.
- *
- * DLM_LKF_ALTCW
- *
- * The same as ALTPR, but the alternate mode is CW.
- *
- * DLM_LKF_FORCEUNLOCK
- *
- * Unlock the lock even if it is converting or waiting or has sublocks.
- * Only really for use by the userland device.c code.

+ * Flags to dlm_lock
+ *
+ * DLM_LKF_NOQUEUE
+ *
+ * Do not queue the lock request on the wait queue if it cannot be granted
+ * immediately.  If the lock cannot be granted because of this flag, DLM will
+ * either return -EAGAIN from the dlm_lock call or will return 0 from
+ * dlm_lock and -EAGAIN in the lock status block when the AST is executed.
+ *
+ * DLM_LKF_CANCEL
+ *
+ * Used to cancel a pending lock request or conversion.  A converting lock is
+ * returned to its previously granted mode.
+ *
+ * DLM_LKF_CONVERT
+ *
+ * Indicates a lock conversion request.  For conversions the name and namelen
+ * are ignored and the lock ID in the LKSB is used to identify the lock.
+ *
+ * DLM_LKF_VALBLK
+ *
+ * Requests DLM to return the current contents of the lock value block in the
+ * lock status block.  When this flag is set in a lock conversion from PW or EX
+ * modes, DLM assigns the value specified in the lock status block to the lock
+ * value block of the lock resource.  The LVB is a DLM_LVB_LEN size array
+ * containing application-specific information.
+ *
+ * DLM_LKF_QUECVT
+ *
+ * Force a conversion request to be queued, even if it is compatible with
+ * the granted modes of other locks on the same resource.
+ *
+ * DLM_LKF_IVVALBLK
+ *
+ * Invalidate the lock value block.
+ *
+ * DLM_LKF_CONVDEADLK
+ *
+ * Allows the dlm to resolve conversion deadlocks internally by demoting the
+ * granted mode of a converting lock to NL.  The DLM_SBF_DEMOTED flag is
+ * returned for a conversion that's been effected by this.
+ *
+ * DLM_LKF_PERSISTENT
+ *
+ * Only relevant to locks originating in userspace.  A persistent lock will not
+ * be removed if the process holding the lock exits.
+ *
+ * DLM_LKF_NODLCKWT
+ *
+ * Do not cancel the lock if it gets into conversion deadlock.
+ * Exclude this lock from being monitored due to DLM_LSFL_TIMEWARN.
+ *
+ * DLM_LKF_NODLCKBLK
+ *
+ * net yet implemented
+ *
+ * DLM_LKF_EXPEDITE
+ *
+ * Used only with new requests for NL mode locks.  Tells the lock manager
+ * to grant the lock, ignoring other locks in convert and wait queues.
+ *
+ * DLM_LKF_NOQUEUEBAST
+ *
+ * Send blocking AST's before returning -EAGAIN to the caller.  It is only
+ * used along with the NOQUEUE flag.  Blocking AST's are not sent for failed
+ * NOQUEUE requests otherwise.
+ *
+ * DLM_LKF_HEADQUE
+ *
+ * Add a lock to the head of the convert or wait queue rather than the tail.
+ *
+ * DLM_LKF_NOORDER
+ *
+ * Disregard the standard grant order rules and grant a lock as soon as it
+ * is compatible with other granted locks.
+ *
+ * DLM_LKF_ORPHAN
+ *
+ * not yet implemented
+ *
+ * DLM_LKF_ALTPR
+ *
+ * If the requested mode cannot be granted immediately, try to grant the lock
+ * in PR mode instead.  If this alternate mode is granted instead of the
+ * requested mode, DLM_SBF_ALTMODE is returned in the lksb.
+ *
+ * DLM_LKF_ALTCW
+ *
+ * The same as ALTPR, but the alternate mode is CW.
+ *
+ * DLM_LKF_FORCEUNLOCK
+ *
+ * Unlock the lock even if it is converting or waiting or has sublocks.
+ * Only really for use by the userland device.c code.

+ * @n:                  Number of slots (registers).
+ * @size:               Size in bytes of a slot (register).
+ * @align:              Required alignment, in bytes.
+ * @bias:               Bias from natural indexing.
+ * @core_note_type:     ELF note @n_type value used in core dumps.
+ * @get:                Function to fetch values.
+ * @set:                Function to store values.
+ * @active:             Function to report if regset is active, or %NULL.
+ * @writeback:          Function to write data back to user memory, or %NULL.
+ *
+ * This data structure describes a machine resource we call a register set.
+ * This is part of the state of an individual thread, not necessarily
+ * actual CPU registers per se.  A register set consists of a number of
+ * similar slots, given by @n.  Each slot is @size bytes, and aligned to
+ * @align bytes (which is at least @size).
+ *
+ * These functions must be called only on the current thread or on a
+ * thread that is in %TASK_STOPPED or %TASK_TRACED state, that we are
+ * guaranteed will not be woken up and return to user mode, and that we
+ * have called wait_task_inactive() on.  (The target thread always might
+ * wake up for SIGKILL while these functions are working, in which case
+ * that thread's user_regset state might be scrambled.)
+ *
+ * The @pos argument must be aligned according to @align; the @count
+ * argument must be a multiple of @size.  These functions are not
+ * responsible for checking for invalid arguments.
+ *
+ * When there is a natural value to use as an index, @bias gives the
+ * difference between the natural index and the slot index for the
+ * register set.  For example, x86 GDT segment descriptors form a regset;
+ * the segment selector produces a natural index, but only a subset of
+ * that index space is available as a regset (the TLS slots); subtracting
+ * @bias from a segment selector index value computes the regset slot.
+ *
+ * If nonzero, @core_note_type gives the n_type field (NT_* value)
+ * of the core file note in which this regset's data appears.
+ * NT_PRSTATUS is a special case in that the regset data starts at
+ * offsetof(struct elf_prstatus, pr_reg) into the note data; that is
+ * part of the per-machine ELF formats userland knows about.  In
+ * other cases, the core file note contains exactly the whole regset
+ * (@n * @size) and nothing else.  The core file note is normally
+ * omitted when there is an @active function and it returns zero.

+ * Universal addresses are introduced in RFC 1833 and further spelled
+ * out in RFC 3530.  RPCBIND_MAXUADDRLEN defines a maximum byte length
+ * of a universal address for use in allocating buffers and character
+ * arrays.
+ *
+ * Quoting RFC 3530, section 2.2:
+ *
+ * For TCP over IPv4 and for UDP over IPv4, the format of r_addr is the
+ * US-ASCII string:
+ *
+ *      h1.h2.h3.h4.p1.p2
+ *
+ * The prefix, "h1.h2.h3.h4", is the standard textual form for
+ * representing an IPv4 address, which is always four octets long.
+ * Assuming big-endian ordering, h1, h2, h3, and h4, are respectively,
+ * the first through fourth octets each converted to ASCII-decimal.
+ * Assuming big-endian ordering, p1 and p2 are, respectively, the first
+ * and second octets each converted to ASCII-decimal.  For example, if a
+ * host, in big-endian order, has an address of 0x0A010307 and there is
+ * a service listening on, in big endian order, port 0x020F (decimal
+ * 527), then the complete universal address is "10.1.3.7.2.15".
+ *
+ * ...
+ *
+ * For TCP over IPv6 and for UDP over IPv6, the format of r_addr is the
+ * US-ASCII string:
+ *
+ *      x1:x2:x3:x4:x5:x6:x7:x8.p1.p2
+ *
+ * The suffix "p1.p2" is the service port, and is computed the same way
+ * as with universal addresses for TCP and UDP over IPv4.  The prefix,
+ * "x1:x2:x3:x4:x5:x6:x7:x8", is the standard textual form for
+ * representing an IPv6 address as defined in Section 2.2 of [RFC2373].
+ * Additionally, the two alternative forms specified in Section 2.2 of
+ * [RFC2373] are also acceptable.
