Hi,

please add commit 848c23b78fafdcd3270b ("btrfs: Remove false alert when fiemap range is smaller than on-disk extent") to the 4.9.x stable tree. It fixes a (harmless) warning but that's causing noise and false alerts, we got a user report.

The warning was introduced by backport to v4.9.136 (commit id in stable tree is 4b1cfa2e9db6168bcbcc). No other stable trees are affected.

The patch applies cleanly on 4.9.158.

Now queued up, thanks.
