Subject: Remove CLONE_VM flag
X-Git-Tag: v2.0-pre17~16
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=9beed4cb465347c778e4f982c330cef78f2628b7;p=lttng-tools.git

Remove CLONE_VM flag

Makes debugging with GDB impossible. We'll have to revisit the actual
performance impact of not having CLONE_VM in place eventually.
