Yes, the kernel is complaining that the file system looks corrupt.
The xfstest generic/001 is the easist one to trigger it:

generic/001 18s ...	[17:35:49][   26.793766] EXT4-fs error (device vde): ext4_mb_generate_buddy:756: group 1, 32763 clusters in bitmap, 32764 
in gd; block bitmap corrupt.
 [17:36:09] 20s
[   39.636943] EXT4-fs (vde): warning: mounting fs with errors, running e2fsck is recommended

I this was using a freshly generated file system using a 20 GiB test
partition, formatted using:

	   mke2fs -t ext4 -O bigalloc /dev/vde

Dropping the patch made the error go away.

Cheers,
