unlockable_mem(5)		   OBSOLETE		     unlockable_mem(5)

NAME
       unlockable_mem - OBSOLETE kernel tunable parameter

DESCRIPTION
       The tunable is obsolete and has been removed.

       Memory  locking	allows the privileged user to specify which pages need
       to remain in memory, and unaffected by the swap process.	 This  feature
       allows  you to ensure that memory access times are unaffected by delays
       introduced by memory paging and swapping.  For example,	locking	 is  a
       tool provided to privileged users on a system that is short on physical
       memory.	Instead of having these privileged  processes  swap  like  the
       rest  of	 the processes, they can lock portions of their address space.
       Once the pages are locked in for the privileged processes, they will no
       longer  have  to	 worry about memory contention.	 The unprivileged pro‐
       cesses however, will have to compete for memory.

       provides you with a limiting factor on  this  privileged	 behavior,  by
       setting the amount of memory which cannot be locked by user processes.

WARNINGS
       Installation of optional kernel software, from HP or other vendors, may
       cause changes to tunable parameter values.   After  installation,  some
       tunable	parameters may no longer be at the default or recommended val‐
       ues.  For information about the effects of installation on tunable val‐
       ues, consult the documentation for the kernel software being installed.
       For  information	 about	optional  kernel  software  that  was  factory
       installed on your system, see at
