Subject: fix: tie compaction probe build to CONFIG_COMPACTION
X-Git-Tag: v2.12.10~2
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=e28ca43f665181c96531e90958fda734a857542b;p=lttng-modules.git

fix: tie compaction probe build to CONFIG_COMPACTION

The definition of 'struct compact_control' in 'mm/internal.h' depends on
CONFIG_COMPACTION being defined. Only build the compaction probe when
this configuration option is enabled.

Thanks to Bruce Ashfield <bruce.ashfield@gmail.com> for reporting this
issue.
