Subject: [PATCH 524/526] open-behind: fix call_frame leak
|
|
|
d2787b |
|
|
|
d2787b |
When an open was delayed, a copy of the frame was created because the
|
|
|
d2787b |
current frame was used to unwind the "fake" open. When the open was
|
|
|
d2787b |
actually sent, the frame was correctly destroyed. However if the file
|
|
|
d2787b |
was closed before needing to send the open, the frame was not destroyed.
|
|
|
d2787b |
|
|
|
d2787b |
This patch correctly destroys the frame in all cases.
