Excessive KDSETMODE ioctls

[Daniel Drake]

Hi,

I noticed that plymouth generates a zillion KDSETMODE(graphics) ioctls
when animating. Not harmful, but doesn't seem quite right.

Here's a trace:
#0  ply_terminal_set_mode (terminal=0x24100, mode=PLY_TERMINAL_MODE_GRAPHICS)
    at ply-terminal.c:766
#1  0xb6e13a3a in flush_head (head=0x45f08, backend=0x378e0)
    at ./plugin.c:1057
#2  flush_head (backend=0x378e0, head=0x45f08) at ./plugin.c:1043
#3  0xb6fa885e in ply_renderer_flush_head (renderer=0x24248, head=0x45f08)
    at ply-renderer.c:342
#4  0xb6fa50ba in ply_pixel_display_flush (display=<optimized out>)
    at ply-pixel-display.c:103
#5  ply_pixel_display_flush (display=<optimized out>)
    at ply-pixel-display.c:115
#6  ply_pixel_display_unpause_updates (display=<optimized out>)
    at ply-pixel-display.c:121

Looks like flush_head is called for every frame and calls
ply_terminal_set_mode() each time. Is there a good reason for this?

Thanks
Daniel
