2018-03-22rcar-gen3: systemd: Do not save file descriptors when restarting WestonKhang Nguyen1-0/+10
In systemd v234, systemd-logind may now be restarted without losing state, it stores the file descriptors (fd) for devices it manages in the system manager. [1] In graphic and multimedia configuration, above feature causes memory leak with the use case of restarting Weston: | root@salvator-x:~# cat /proc/meminfo | grep Cma | CmaTotal: 671744 kB | CmaFree: 629788 kB | root@salvator-x:~# | root@salvator-x:~# systemctl restart weston | root@salvator-x:~# | root@salvator-x:~# cat /proc/meminfo | grep Cma | CmaTotal: 671744 kB | CmaFree: 599404 kB Because the system continues allocating memory for the new session during the previous device fds still open. This commit avoids saving device fds into the system manager by setting "FileDescriptorStoreMax=0" [2] in "systemd-logind.service".
