Re: Testers needed for LTTng 0.6.0pre8

Hi,

Just to make sure, do a git-pull from the git tree, the following commit fixes a
problem with probes built-in.

See :
http://ltt.polymtl.ca/cgi-bin/gitweb.cgi?p=linux-2.6-lttng.git;a=commit;h=f580959abc3060e0b13eaf1d17df8b6b606ff85d

I am not sure if this commit was on the server or not last Friday morning.

Otherwise, verify that /mnt/debugfs is mounted. See the updated QUICKSTART guide
on the website. (LTTng had moved from relayfs to debugfs).
