Subject: Pass arguments for context size computation
X-Git-Tag: v2.11.0-rc1~36
X-Git-Url: http://git.liburcu.org/?p=lttng-modules.git;a=commitdiff_plain;h=1474c8e2ef816a275305fe975b82ca6c50f5eca7

Pass arguments for context size computation

Pass same arguments to get_size_arg() than to record(). This new
operation has the same effect than get_size(), and the client code can
implement either one.
