It opens both files and then performs the ioctl() call:
ioctl(4, 0x40049409, 0x3) = -1 EINVAL (Invalid argument)

This may not be necessary. If I run strace on bcp, it turns out that its
ioctl() call encounters the same error:
ioctl(3, 0x40049409, 0x4) = -1 EINVAL (Invalid argument)
and thus the suggestion that bcp (by behaving like --reflink=auto) is masking
the issue appears to be exactly on point.
