From: Jonathan Rajotte Date: Tue, 18 May 2021 18:48:37 +0000 (-0400) Subject: Rename lttng_event_rule_kernel_probe to lttng_event_rule_kernel_kprobe X-Git-Tag: v2.13.0-rc3~77 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=d84633c4baef5c02b82c75bd25e859a2a7a96fe3;p=lttng-tools.git Rename lttng_event_rule_kernel_probe to lttng_event_rule_kernel_kprobe The add trigger command now accepts `kernel:kprobe` instead of `kernel- probe`. `kprobe` is still accepted.
