Subject: [PATCH 28/28] usb-redir: Don't try to write to the chardev after a
Justin M. Forbes fc5c27
 close event
Justin M. Forbes fc5c27
Justin M. Forbes fc5c27
Sicne we handle close async in a bh, do_write and thus write can get
Justin M. Forbes fc5c27
called after receiving a close event. This patch adds a check to
Justin M. Forbes fc5c27
the usb-redir write callback to not do a qemu_chr_write on a closed
Justin M. Forbes fc5c27
chardev.
