use #pragma once instead of foo*foo #define guards #pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers 2012-07-18 19:07:51 +02:00			`#pragma once`

mount-setup: change the system mount propagation to shared by default only at bootup The commit b3ac5f8cb987 has changed the system mount propagation to shared by default, and according to the following patch: https://github.com/opencontainers/runc/pull/208 When starting the container, the pouch daemon will call runc to execute make-private. However, if the systemctl daemon-reexec is executed after the container has been started, the system mount propagation will be changed to share again by default, and the make-private operation above will have no chance to execute. 2020-03-23 03:42:46 +01:00			`int mount_setup(bool loaded_policy, bool leave_propagation);`

core: remove JoinControllers= configuration setting This removes the ability to configure which cgroup controllers to mount together. Instead, we'll now hardcode that "cpu" and "cpuacct" are mounted together as well as "net_cls" and "net_prio". The concept of mounting controllers together has no future as it does not exist to cgroupsv2. Moreover, the current logic is systematically broken, as revealed by the discussions in #10507. Also, we surveyed Red Hat customers and couldn't find a single user of the concept (which isn't particularly surprising, as it is broken...) This reduced the (already way too complex) cgroup handling for us, since we now know whenever we make a change to a cgroup for one controller to which other controllers it applies. 2018-11-15 21:07:43 +01:00			`int mount_cgroup_controllers(void);`

split mount_point_is_api() and mount_point_ignore() We should not handle the ignore list as API mounts, as systemd itself never touches them.
