OBSOLETE hdlpreg_hash_locks(5)
(Tunable Kernel Parameters)
NAME
hdlpreg_hash_locks - determines the size of the pregion spinlock pool
DESCRIPTION
This tunable was used in prior releases of HP-UX to determine how many spinlocks to allocate for use in
synchronizing changes to pregion sub-structures. As of HP-UX 11i version 3.0 and later, the sub-
structures are no longer synchronized in this manner and the pool no longer exists. As such, the tunable
is no longer needed and is obsolete as of HP-UX 11i Version 3.0.
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its
meaning changed in future releases of HP-UX.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parame-
ter values. After installation, some tunable parameters may no longer be at the default or recommended
values. For information about the effects of installation on tunable values, consult the documentation for
the kernel software being installed. For information about optional kernel software that was factory
installed on your system, see HP-UX Release Notes at
