Subject: [PATCH 28/28] usb-redir: Don't try to write to the chardev after a
|
||
|
|
close event
|
||
|
|
|
||
|
|
Sicne we handle close async in a bh, do_write and thus write can get
|
||
|
|
called after receiving a close event. This patch adds a check to
|
||
|
|
the usb-redir write callback to not do a qemu_chr_write on a closed
|
||
|
|
chardev.

||
