tracing/boot: Add ftrace.instance.*.alloc_snapshot option
Add ftrace.instance.*.alloc_snapshot option.
This option has been described in Documentation/trace/boottime-trace.rst
but not implemented yet.
ftrace.[instance.INSTANCE.]alloc_snapshot
Allocate snapshot buffer.
The difference from kernel.alloc_snapshot is that the kernel.alloc_snapshot
will allocate the buffer only for the main instance, but this can allocate
buffer for any new instances.
