Setting this parameter to 1 will cause all System V shared me= mory > segments to be mapped to unpageable physical RAM. This feature only has = an > effect if you are either (A) mapping small amounts of shared memory across > many (hundreds) of processes, or (B) mapping large amounts of shared memo= ry > across any number of processes. This feature allows the kernel to remove= a > great deal of internal memory management page-tracking overhead at the co= st of > wiring the shared memory into core, making it unswappable. --=20 You are receiving this mail because: You are the assignee for the bug.=
