It does seem to be something of that sort, as it appears in
https://www.spinics.net/lists/linux-btrfs/msg67281.html
(though as factual csum, not the expected one).

Actually, turns out ALL of those are sqlite files(!)
.mozilla/firefox/.../places.sqlite <- 4 instances (for 4 users)
.moonchild productions/pale moon/.../urlclassifier3.sqlite
.config/chromium/Default/Application Cache/Cache/data_3 <- twice (for 2 users)
.config/chromium/Default/History
.config/chromium/Default/Top Sites
nothing else affected.
Forgot to mention that the kernel version is 4.9.40.

With respect,
