Hi,
After upgrading to 4.0.0-rc5 from 4.0.0-rc4 I see "Object already
exists"
after reboot.
The fs is forced read only.
The error does not disappear after additional reboots.
If you go back to 4.0.0-rc4, does the error still happens?
As mentioned in the email to Chris:
I will try to boot with 4.0.0-rc4 as soon as I get physical access,
and also revert ea526d18990018f224e5734748975bea1824545f.
In order to revert ea526d1899, you need to revert this one first:

Btrfs: prepare block group cache before writing
This second commit relies on the first one, things won't work right
with only one gone.

Thanks,
I would most likely have missed that.

Hi,
Reboot with rc-4 did not fix anything. The same "errno=-17 Object
already exists" was still present.
Reboot with 3.19.0 failed and went straight to initramfs/busybox.
btrfs-zero-log from busybox allowed boot to 3.19.0
Reboot to 4.0.0-rc4 without problems.
touch tmp.file
sync
btrfs fi sync
No issues
Building a new rc-5 with reverts, also no issues.

Reboot into 4.0.0-rc5 with reverts
Same warning and read only fs.
