FREEMAIL_ENVRCPT(0.00)[gmail.com,gmx.de] Clean up the pageref state as part of the lastclose helper. This only requires to clear the page's mapping field. The pageref and page can stay in place for the next opened instance of the frame- buffer file. With the change in the clean-up logic, there's no further need to look up pages during the lastclose cleanup. The code instead uses the existing pagerefs in its look-up table. It also avoids using smem_len, which some driver might not set correctly. v2: - fix typos in commit message (Javier) Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas --- drivers/video/fbdev/core/fb_defio.c | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-) diff --git a/drivers/video/fbdev/core/fb_defio.c b/drivers/video/fbdev/core/fb_defio.c index bff1e300ed6bb..f23b1cbe67192 100644 --- a/drivers/video/fbdev/core/fb_defio.c +++ b/drivers/video/fbdev/core/fb_defio.c @@ -62,6 +62,14 @@ static struct fb_deferred_io_pageref *fb_deferred_io_pageref_lookup(struct fb_in return pageref;

TO_DN_SOME(0.00)[]; FREEMAIL_ENVRCPT(0.00)[gmail.com,gmx.de] Rewrite some docs that are not up-to-date any longer. Remove the TODO item for fbdev-generic conversion, as the helper has been replaced. Make documentation for DMA, SHMEM and TTM emulation available.
