Re: [lttng-dev] [PATCH] Fix mm_vmscan_lru_isolate tracepoint for RHEL 9.4 kernel

[Kienan Stewart via lttng-dev <lttng-dev@lists.lttng.org>]

Hi Martin,

thanks for the patch.

I changed the version range slightly. The RHEL kernel 5.14.0-427.13.1 
still has the `isolate_mode` parameter in the `mm_vmscan_lru_isolate` 
tracepoint; it was only removed in 5.14.0-427.16.1.

I also forward ported the patch to the master branch.

The updated patches will be reviewed at: 
https://review.lttng.org/q/topic:%22buildfix-el9.4%22

thanks,
kienan
