Subject: Disable open[at] bitwise enum in default build
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=f52e9f44f5aa2531aa35d6bd2f3af65c56325e34;p=lttng-modules.git

Disable open[at] 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 c8dfb72431505d5f01a6f090f3f7427d9ca6fe94
  Author: Geneviève Bastien <gbastien@versatic.net>

    syscalls: Make the flags and mode fields of open[at] enumerations

Use the non-override system call tracing implementation when the enum is
not used.
