Hi there
I just uploaded a patch for the POSIX.4 memory locking onto
sunsite. You can find it in /pub/Linux/Incoming.
What does it do?
POSIX.4 defines functions for locking pages in physical memory.
This is done to avoid page faults in realtime applications. These
page faults can lead to extensive waiting times which lead to
failure of the realtime application.
For more information read:
"POSIX.4 - Programming for the real world", Bill O. Gallmeister,
1995, O'Reilly & Associates
I hope I will be able to write a man page soon.
Here's the lsm:
