Subject: Fix: common: hide shm* util symbols
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5fad4ed508b20b7850dc8333c55afeed6737d08c;p=lttng-tools.git

Fix: common: hide shm* util symbols

Internal symbols that are part of libcommon must be marked as "hidden".
Otherwise, the symbols are exported as part of liblttng-ctl.so.
