Subject: [PATCH] mount-setup: fix segfault in mount_cgroup_controllers when
|
|
using gcc9 compiler
|
|
|
|
According to the documentation:
|
|
https://gcc.gnu.org/gcc-9/porting_to.html#complit
|
|
|
|
The 'join_controllers' that relied on the extended lifetime needs
|
|
to be fixed, move the compound literals to the function scope it
|
|
need to accessible in.
|
|
|
|
Resolves: #1868877
