This tests the sysfs publishing for btrfs allocation and device
membership info under a number of different layouts, similar to the
btrfs replace test. We test the allocation files only for existence and
that they contain numerical values. We test the device membership
by mapping the devices used to create the file system to sysfs paths
and matching them against the paths used for the device membership
symlinks.

Since this is a new feature, it passes on kernels without
a /sys/fs/btrfs/<fsid> directory.

I don't think you need the extra udevadm here.  Thanks,
