Subject: Fix: syscall event rule: emission sites not compared in is_equal
X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=8ab63dfb6a51460c9744828f7248d0fdca602ad3

Fix: syscall event rule: emission sites not compared in is_equal

The emission sites are not compared when comparing two kernel-syscall
event rules. This prevents users from subscribing to notifications of
triggers that use event-rule-matches syscall conditions which differ
only by their emission site (entry, exit, entry+exit).
