From: Michael Jeanson Date: Tue, 11 May 2021 20:16:18 +0000 (-0400) Subject: Disable clone bitwise enum in default build X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=f56826ae38982a29930df599228e8cc6e5f4b46b;p=lttng-modules.git Disable clone bitwise enum in default build Only generate the bitwise enumerations when CONFIG_LTTNG_EXPERIMENTAL_BITWISE_ENUM is enabled, so the default build does not generate traces which lead to warnings when viewed with babeltrace 1.x and babeltrace 2 with default options. Original commit: commit d775625e2ba4825b73b5897e7701ad6e2bdba115 Author: Geneviève Bastien Date: Wed Apr 1 14:31:49 2020 -0400 syscalls: Make clone()'s `flags` field a 2 enum struct.
