Subject: [PATCH] util: avoid double close of fd
|
|
|
|
We could end with a double close if we close the fd loop and flush_fd
|
|
fails. That would make us goto fail and there we close the fd once
|
|
again. This patch sets the fd to the return value for safe_close: -1
|
|
A fd with negative value will be ignored by the next call to
|
|
safe_close.
