[ Upstream commit 2fc60e2ff972d3dca836bff0b08cbe503c4ca1ce ]
$number + > bash means redirect FD $number, e.g. commonly used 2> redirects stderr (fd 2). The test uses 8192> to write the number 8192 to a file, this results in:
./devlink.sh: line 499: 8192: Bad file descriptor
Oddly the test also papers over this issue by checking for failure (expecting an error rather than success) so it passes, anyway.
