Feature #1067: Update writeback instrumentation for newer kernels
global_dirty_limit symbol lookup failed.
Added by Julien Desfossez over 8 years ago.

Description
On Ubuntu 16.04 with the current kernel (4.4.0-31-generic) and lttng-modules current master, we see this message in dmesg:
global_dirty_limit symbol lookup failed.
It can be quite frequent, enough to notice some additional activity on the syslog.
In addition to fixing this issue, we should also make sure it is only output once.
