Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: quoted-printable Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Hi there, Is there a way to prevent some page (data, possibly dynamically assigned) from a process to be swapped ? I've heard it was possible but how ? I beleive the sticky bit was used historically to prevent a whole process to be swapped. What is the precise meaning of it ? The usage I intend is to avoid swapping sensitive data like Crypto keys, so locking the whole process in memory is not realy useful.
