From 5b41535aac0c07135ff6a4c5c2ae115d1c20c0bc Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Wed, 24 Mar 2010 16:11:29 +0100 Subject: rlimits: redo do_setrlimit to more generic do_prlimit It now allows also reading of limits. I.e. all read and writes will later use this function. It takes two parameters, new and old limits which can be both NULL. If new is non-NULL, the value in it is set to rlimits. If old is non-NULL, current rlimits are stored there. If both are non-NULL, old are stored prior to setting the new ones, atomically. (Similar to sigaction.)
