There's compilation error when building lxc for ARM/ARM64 BSPs.
The error message is as below:
| ../git/src/lxc/cgroups/cgfsng.c🔢111: error: incompatible
type for argument 10 of 'sd_bus_call_method_asyncv'
The 10th argument is of type va_list but NULL is supplied, thus causing
compilation error.
So we use sd_bus_call_method_async to replace the asyncv one to
solve this issue.

Subject: [PATCH] use sd_bus_call_method_async to replace the asyncv one
|
|
|
|
The sd_bus_call_method_asyncv's 10th parameter is of type
|
|
va_list and supplying NULL when invoking it causes compilation
|
|
error. Just replace it with the async one.
