You can safely use btrfs_warn here.


right. I tried to know what to use before, but wasn't sure.

There's already btrfs_error used in the function. The only context where
the message macros are not usable is during mount when fs_info is not
available.

would you be
able to accept it as it is ? OR I can send a new patch to correct this.
Just that changing this commit would fail further commits like
    Btrfs: sysfs: support seed devices in the sysfs layout.

But this patch also needs to apply the same sort of change, please
resend. Thanks.

I got this in my local ws. Will be sending it out.
