commit c117e7b103d3a0ce8bb32682997b60de20faf3f3 Author: Juergen Gross <jgross@xxxxxxxx> AuthorDate: Sun Jan 16 09:33:17 2022 +0100 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Tue Jan 18 18:26:43 2022 +0000 remove event channel specific struct file definitions The event channel specific union member in struct file is no longer needed, so remove it together with the associated structure definitions. The event channel file type and its associated handling can be removed, too, as libxenevtchn is now supplying a struct file_ops via a call of alloc_file_type(). This removes all contents of CONFIG_LIBXENEVTCHN guarded sections, so this config option can be removed. Add an extern declaration for event_queue as it is used by libxenevtchn.
