There's a long-standing bug in defio where the framebuffer device or
module gets removed while mmap'ed areas of the framebuffer memory
persists in userspace. Page faults in the area then operate on defined
state.
Patches 1 and 2 fix these problems. Patches 3 and 4 build upon the fix
and put defio state into the correct places.
Thomas Zimmermann (4):
fbdev: defio: Disconnect deferred I/O from the lifetime of struct
fb_info
fbdev: defio: Keep module reference from VMAs
fbdev: defio: Move variable state into struct fb_deferred_io_state
fbdev: defio: Move pageref array to struct fb_deferred_io_state
