- *
- * This queries metadata about a framebuffer. User-space fills
- * &drm_mode_fb_cmd2.fb_id as the input, and the kernels fills the rest of the
- * struct as the output.
- *
- * If the client is DRM master or has &CAP_SYS_ADMIN, &drm_mode_fb_cmd2.handles
- * will be filled with GEM buffer handles. Fresh new GEM handles are always
- * returned, even if another GEM handle referring to the same memory object
- * already exists on the DRM file description. The caller is responsible for
- * removing the new handles, e.g. via the &DRM_IOCTL_GEM_CLOSE IOCTL. The same
- * new handle will be returned for multiple planes in case they use the same
- * memory object. Planes are valid until one has a zero handle -- this can be
- * used to compute the number of planes.
- *
- * Otherwise, &drm_mode_fb_cmd2.handles will be zeroed and planes are valid
- * until one has a zero &drm_mode_fb_cmd2.pitches.
- *
- * If the framebuffer has a format modifier, &DRM_MODE_FB_MODIFIERS will be set
- * in &drm_mode_fb_cmd2.flags and &drm_mode_fb_cmd2.modifier will contain the
- * modifier. Otherwise, user-space must ignore &drm_mode_fb_cmd2.modifier.
- *
- * To obtain DMA-BUF FDs for each plane without leaking GEM handles, user-space
- * can export each handle via &DRM_IOCTL_PRIME_HANDLE_TO_FD, then immediately
- * close each unique handle via &DRM_IOCTL_GEM_CLOSE, making sure to not
- * double-close handles which are specified multiple times in the array.

- * DRM_IOCTL_MODE_CLOSEFB - Close a framebuffer.
- *
- * This closes a framebuffer previously added via ADDFB/ADDFB2. The IOCTL
- * argument is a framebuffer object ID.
- *
- * This IOCTL is similar to &DRM_IOCTL_MODE_RMFB, except it doesn't disable
- * planes and CRTCs. As long as the framebuffer is used by a plane, it's kept
- * alive. When the plane no longer uses the framebuffer (because the
- * framebuffer is replaced with another one, or the plane is disabled), the
- * framebuffer is cleaned up.
- *
- * This is useful to implement flicker-free transitions between two processes.
- *
- * Depending on the threat model, user-space may want to ensure that the
- * framebuffer doesn't expose any sensitive user information: closed
- * framebuffers attached to a plane can be read back by the next DRM master.
