Subject: [PATCH] zfsinfo: Correct a check for error allocating memory
|
|
|
468bd4 |
|
|
|
468bd4 |
While arguably the check for grub_errno is correct, we should really be
|
|
|
468bd4 |
checking the return value from the function since it is always possible
|
|
|
468bd4 |
that grub_errno was set elsewhere, making this code behave incorrectly.
