Hi,

Pages kept in memory for the lifetime of a process by means of a system call (such as mlock, plock, or shmctl) are termed locked memory. Locked memory cannot be paged and processes with locked memory cannot be deactivated. Typically, locked memory holds frequently accessed programs or data structures, such as critical sections of application code. Keeping them memory-resident improves application performance.
