Change subject: add osmo_stats_report_lock api ...................................................................... Patch Set 1: (4 comments) Patchset: PS1: > I think with this you are only sorting out one of the concurrency problems > when using rate_ctr/stats […] How the caller chooses to use this remains very specialized for an application, the main aim is to allow a hook to mutex around the stats reporting. The way this is used in my hnbgw patch: The main thread simply also holds a osmo_stats_report_lock() while groups are added/removed. Because the counter-retrieving thread acquires osmo_stats_report_lock() when updating counters, things are guarded.

[…] good point https://gerrit.osmocom.org/c/libosmocore/+/36538/comment/37dcc5d3_51ee4c81 PS1, Line 819: void osmo_stats_report_lock(bool lock) > I'd definetly have 2 APIs here, one for lock and one for unlock.
