Btrfs warnings in kernel 4.13.5

Hi, I've upgraded my system to Fedora 27 and now I see many btrfs warnings, although the system seems to be working fine. Is this something I should worry about? I have a scrub running with no errors so far: # btrfs scrub status /mnt/btrfs scrub status for 038b2b48-fd2d-4565-b2b1-d07847ecca8c

[BUG] unable to handle kernel NULL pointer dereference when removing device

Hello, I've hit this bug when removing the device /dev/mapper/vg_hd04-lv_btrfs_hd04 from this filesystem. The only peculiarity is that it mixes partitions and a lvm logical volume. The device was removed successfully and no further errors have been seen. # btrfs fi show Label: 'btrfs_raid1'

Usage of new added disk not updated while doing a balance

Hello, I have added a new disk to my filesystem and I'm doing a balance right now, but I'm a bit worried that the disk usage does not get updated as it should. I remember from earlier versions that you could see the disk usage being balanced across all disks. These are the commands I've run: #

File capabilities are lost when sending/receiving a btrfs subvolume

Hello, I noticed that file capabilites are lost on received subvolumes, so I opened the bug report #68891 [1]. I don't know if other xattrs are affected by this problem. I just like to know if fixing this issue is under the radar of the developers. Thank you. [1]

Another crash when deleting a large number of snapshots

This kind of crashes happens me very often when I delete a large number (+200) of snapshots at once. There is a very high IO for a while, and after that, the system freezed at intervals. I had to reboot the system to get it responsive again. Versions used: kernel-3.13.6-200.fc20.x86_64
