[Qemu-devel] [PATCH v2 1/2] qcow2: Correct comment for realloc_refcount_block() |
Date: |
Mon, 17 Mar 2014 23:04:51 +0100 |
Contrary to the comment describing this function's behavior, it does not
return 0 on success, but rather the offset of the newly allocated
cluster. This patch adjusts the comment accordingly to reflect the
actual behavior.
