Zdenek Kabelac	2f5ea9e61a	exported_symbols: comment old symbols ... Fix versioning for updated symbols dm_stats_create_region and dm_stats_create_region. Only the latest symbol should have global entry. Since I'm not sure what is currenlty the best option for old symbols - we added support for easy commenting of them (so we do not lose information when the symbol appeared for the first time.) Note: some old already deleted symbols should have been restored as comments.	2019-08-09 12:57:07 +02:00
Bryn M. Reeves	567189cc76	libdm: add per region precise timestamps property methods	2015-08-24 20:03:21 +01:00
Bryn M. Reeves	f4262026b6	libdm: add precise timestamps support to libdm-stats ... Add support for the kernel precise_timestamps feature. This allows regions to be created using counters with nanosecond precision. A new dm_stats method, dm_stats_set_precise_timestamps() causes all future regions created with this handle to attempt to enable precise counters.	2015-08-24 20:03:21 +01:00
Bryn M. Reeves	386e91addb	libdm: add dm_message_supports_precise_timestamps() ... Add a function to test whether the kernel precise_timestamps feature is available in the current device-mapper driver version. Presence of precise_timestamps also implies the availability of latency histograms.	2015-08-20 12:11:23 +01:00
