From 436f640717bab63240d9a624846d947e150a2cee Mon Sep 17 00:00:00 2001 From: Mathieu Desnoyers Date: Tue, 17 Dec 2019 09:27:54 -0500 Subject: [PATCH] lttng-abi: Document ioctl numbers reserved by lttng-abi-old.h Document the ioctl numbers reserved by lttng-abi-old.h in the (relatively) new lttng-abi.h, so they are taken into account when assining numbers to new lttng ioctl commands.
