Subject: Tests: fix: uninitialized values passed to close() on error
X-Git-Tag: v2.12.0-rc1~395
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=7f6288c8728f0a161456f4b86e4e4b513104723b;p=lttng-tools.git

Tests: fix: uninitialized values passed to close() on error

The fds array is not initialized resulting in uninitialized file
descriptors being passed to close() when an error is encountered in
the epoll-setting loop.
