linux-stable.git/include/media, branch linux-2.6.25.y Linux kernel stable tree bttv: Fix a deadlock in the bttv driver 2008-06-16T20:20:06+00:00 Arjan van de Ven arjan@linux.intel.com 2008-05-20T16:53:52+00:00 69f24455cf25d776f8b19d06c7a43a8185fc633d commit 81b2dbcad86732ffc02bad87aa25c4651199fc77 in mainline. vidiocgmbuf() does this: mutex_lock(&fh->cap.vb_lock); retval = videobuf_mmap_setup(&fh->cap, gbuffers, gbufsize, V4L2_MEMORY_MMAP); and videobuf_mmap_setup() then just does mutex_lock(&q->vb_lock); ret = __videobuf_mmap_setup(q, bcount, bsize, memory); mutex_unlock(&q->vb_lock); which is an obvious double-take deadlock. This patch fixes this by having vidiocgmbuf() just call the __videobuf_mmap_setup function instead.

commit 81b2dbcad86732ffc02bad87aa25c4651199fc77 in mainline.

vidiocgmbuf() does this:
        mutex_lock(&fh->cap.vb_lock);
        retval = videobuf_mmap_setup(&fh->cap, gbuffers, gbufsize,
                                     V4L2_MEMORY_MMAP);

and videobuf_mmap_setup() then just does
        mutex_lock(&q->vb_lock);
        ret = __videobuf_mmap_setup(q, bcount, bsize, memory);
        mutex_unlock(&q->vb_lock);

which is an obvious double-take deadlock.

This patch fixes this by having vidiocgmbuf() just call the
__videobuf_mmap_setup function instead.

V4L/DVB (7133): Fix Kconfig dependencies 2008-02-18T14:14:53+00:00 Mauro Carvalho Chehab mchehab@infradead.org 2008-02-02T14:25:31+00:00 057596eea8402aa8f7a670bf3195665aa8267204 As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes. This patch moves the functions that videodev needs from v4l2-common. It also fixes some Kconfig changes. After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked into kernel. v4l2-common will be m, and all V4L drivers will also be m. This approach is very conservative, since it is possible to have V4L drivers that don't need I2C or v4l2-common. The better is to map what drivers really need v4l2-common, making them to select v4l2-common, and allowing the others to be 'y', 'm' and 'n'.
