2008-02-18V4L/DVB (7121): Renames videobuf lock to vb_lockMauro Carvalho Chehab
This helps to identify where vb_lock is being used, and find missusages of the locks. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-12-11V4L/DVB (6751): V4L: Memory leak! Fix count in videobuf-vmalloc mmapBrandon Philips
This is pretty serious bug. map->count is never initialized after the call to kmalloc making the count start at some random trash value. The end result is leaking videobufs. Also, fix up the debug statements to print unsigned values.

Breaks on any target that has copy_to_user() defined as a non-trivial macro. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-10-10V4L/DVB (6292): videobuf_core init always require callback implementationMauro Carvalho Chehab
In the past, videobuf_queue_init were used to initialize PCI DMA videobuffers. This patch renames it, to avoid confusion with the previous kernel API, doing: s/videobuf_queue_init/void videobuf_queue_core_init/ Also, the operations is now part of the function parameter. The function will also add a test if this is defined, otherwise producing BUG. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-10-10V4L/DVB (6254): Add videobuf-vmallocMauro Carvalho Chehab
Adds a newer videobuf-vmalloc module. This module uses the same videobuf controls, but implements memory allocation based on vmalloc methods. With this method, an USB driver can use video-buf, without needing to request memory from the DMA-safe area. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
