Subject: urcu-bp: no need for weak attribute
X-Git-Tag: v0.6.7~3
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=125ea9db85e434dfb5f9753ea37997bb9ae4fce8;p=userspace-rcu.git

urcu-bp: no need for weak attribute

We should do this within the user (e.g. liblttng-ust), not within the
urcu-bp library.
