  "message": "drm: refcnt drm_framebuffer (v4.1)\n\nThis simplifies drm fb lifetime, and if the crtc/plane needs to hold\na ref to the fb when disabling a pipe until the next vblank, this\navoids the need to make disabling an overlay synchronous.  This is a\nproblem that shows up when userspace is using a drm plane to\nimplement a hw cursor.. making overlay disable synchronous causes\na performance problem when x11 is rapidly enabling/disabling the\nhw cursor.  But not making it synchronous opens up a race condition\nfor crashing if userspace turns around and immediately deletes the\nfb.  Refcnt\u0027ing the fb makes it possible to solve this problem.\n\nv1: original\nv2: add drm_framebuffer_remove() which is called in all paths where\n    fb-\u003efuncs-\u003edestroy() was directly called before.  This cleans\n    up the CRTCs/planes that the fb was attached to.  You should\n    only directly use drm_framebuffer_unreference() if you are also\n    using drm_framebuffer_reference() to keep a ref to the fb.\nv3: add comment explaining the fb refcount\nv4: remove duplicate \u0027list_del(\u0026fb-\u003efilp_head)\u0027\n\n[airlied: v4.1: fix local rejection]\n\nSigned-off-by: Rob Clark \u003crob@ti.com\u003e\nSigned-off-by: Dave Airlie \u003cairlied@redhat.com\u003e\n",
