Quoting Александр Берсенев <[email protected]>:
Hello,
I use task/cgroup plugin. When I enabling ConstrainDevices=yes in
cgroups.conf tasks refuses to run.
The error is: sinfo: bitstring.c:238: bit_nclear: Assertion `(start) <
((b)[1])' failed.
The error occurs while calling
gres_conf_lines = gres_plugin_node_config_devices_path(dev_path,
gres_name, PATH_MAX);
from src/plugins/task/cgroup/task_cgroup_devices.c.
This function assumes that another function
gres_plugin_node_config_load was called before.
I've added gres_plugin_node_config_load call into
task_cgroup_devices_init function and problem disappears. The patch is
in attachment.
