Revision 4d572d9f46507be8cfe326aa5bc3698babcbdfa7 authored by Avi Kivity on 08 June 2018, 19:12:32 UTC, committed by Al Viro on 15 June 2018, 00:07:38 UTC 
eventfd: only return events requested in poll_mask()
 
The ->poll_mask() operation has a mask of events that the caller
is interested in, but we're returning all events regardless.

Change to return only the events the caller is interested in. This
fixes aio IO_CMD_POLL returning immediately when called with POLLIN
on an eventfd, since an eventfd is almost always ready for a write.

	help
	  Minix is a simple operating system used in many classes about OS's.
	  The minix file system (method to organize files on a hard disk
	  partition or a floppy disk) was the original file system for Linux,
	  but has been superseded by the second extended file system ext2fs.
	  You don't want to use the minix file system on your hard disk
	  because of certain built-in restrictions, but it is sometimes found
	  on older Linux floppy disks.  This option will enlarge your kernel
	  by about 28 KB. If unsure, say N.

	  To compile this file system support as a module, choose M here: the
	  module will be called minix.  Note that the file system of your root
	  partition (the one containing the directory /) cannot be compiled as
	  a module.
