Subject: Fix: session_find_by_id can return NULL legitimately
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=d68ec9741e83c99eea549243eec46c37b4eea61f;hp=d68ec9741e83c99eea549243eec46c37b4eea61f;p=lttng-tools.git

Fix: session_find_by_id can return NULL legitimately

session_find_by_id can return NULL when the backing hash table
is NULL. This is not an error in the context of
its caller, save_per_pid_lost_discarded_counters(), since the
ltt_session can be destroyed before an ust app session is torn down.

See the comment in save_per_pid_lost_discarded_counters() for more
information.
