Hey.

Just got the following with 4.12.6:

Aug 21 03:29:51 heisenberg kernel: BTRFS warning (device dm-0): unhandled fiemap cache detected: offset=0 phys=812641906688 len=12288 flags=0x0

Aug 21 03:30:58 heisenberg kernel: BTRFS warning (device dm-0): unhandled fiemap cache detected: offset=0 phys=813760614400 len=32768 flags=0x0
Aug 21 03:31:15 heisenberg kernel: BTRFS warning (device dm-0): unhandled fiemap cache detected: offset=0 phys=812641906688 len=12288 flags=0x0

Is it what should be fixed with:
https://patchwork.kernel.org/patch/9803291/

?

Is this harmless or must I assume that some part of my data/fs is now
corrupt and should I recover from backup?

Thanks,
Chris.
