Juergen Gross 51c23bd691 xen/evtchn: avoid WARN() when unbinding an event channel ... When unbinding a user event channel, the related handler might be called a last time in case the kernel was built with CONFIG_DEBUG_SHIRQ. This might cause a WARN() in the handler. Avoid that by adding an "unbinding" flag to struct user_event which will short circuit the handler. Fixes: 9e90e58c11 ("xen: evtchn: Allow shared registration of IRQ handers") Reported-by: Demi Marie Obenour <demi@invisiblethingslab.com> Tested-by: Demi Marie Obenour <demi@invisiblethingslab.com> Signed-off-by: Juergen Gross <jgross@suse.com> Reviewed-by: Oleksandr Tyshchenko <oleksandr_tyshchenko@epam.com> Link: https://lore.kernel.org/r/20240313071409.25913-2-jgross@suse.com Signed-off-by: Juergen Gross <jgross@suse.com>		2024-03-17 18:57:11 +01:00
