Prior to the v5.10-based StarlingX kernel, the "#ifdef CONFIG_SIGEXIT"
guard in prctl.h would require the user-space to either define the
CONFIG_SIGEXIT macro, or define the PR_DO_NOTIFY_TASK_STATE macro *and*
the task_state_notify_info structure to avoid build failures. The
service manager code had taken the latter approach.
Now that the prctl.h header file has been fixed in the v5.10-based
kernel to not guard these user-space APIs with "#ifdef CONFIG_SIGEXIT",
the service manager is encountering the following compilation errors:
sm_process_death.c:49:8: error: redefinition of \
'struct task_state_notify_info'
struct task_state_notify_info
^
In file included from /usr/include/sys/prctl.h:22:0,
from sm_process_death.c:18:
/usr/include/linux/prctl.h:76:8: error: previous definition of \
'struct task_state_notify_info'
struct task_state_notify_info {
^
This commit avoids these errors by detecting whether the
PR_DO_NOTIFY_TASK_STATE macro has already been defined, which ought to
preserve backwards compatibility with older StarlingX kernels.
