From: Yunjian Wang <[email protected]>The issue is that a file descriptor at 0 is a valid one. Currently the file not found, the return value will be set to 0. As a result, it is impossible to distinguish between a correct descriptor and a failed return value. Fix it to return -ENOENT instead of 0.
