Hi,
The usual setup: vanilla torvalds tree kernel 6.6-rc2, Ubuntu 22.04 LTS.
KCSAN had found a number of data-races in the btrfs implementation.
It is not clear whether this can lead to the corruption of data on the storage media.
Please find the complete KCSAN dmesg report attached.
Best regards,
Mirsad Todorovac

Hi,
Thank you for your insight.
Yes, I see that it is the old report ... Mea culpa. But now I had more
instances and perhaps they can give more insight?
I must admit that I am a bit perplexed with the KCSAN reports data races
in hundreds.
Most of them were connected with the find_*_bit() family of functions
and ACPI. Eliminating those races might fix like 80% of the KCSAN
reported bugs.
Best regards,
Mirsad Todorovac

This isn't btrfs; it's the same as the race reported on August 18th.
