Hi, OK, correction, the probes from the io provider are correctly triggered with forcedirectio enabled but only once !
Here is where I am : Let create a file with mkfile 100m <path> fbt:ufs:directio_start:entry probe is fired multiple times but the probes from the io provider are only fired once each. Like this : [...] 20 4641 bdev_strategy:start io start 20 4631 biowait:wait-start io wait-start 20 4630 biowait:wait-done io wait-done 21 4629 biodone:done io done [...] io:::start is triggered at the beginning of the mkfile call and nothing afterward. So going back to the beginning of my problem (which is having io stats on a forectdirectio mounted partition); I'm still wondering how to do that... If you have some hints...

Yes, but we're wondering why io:::start isn't firing.
