sbp2util_mark_command_completed takes a lock which was already taken by sbp2scsi_complete_all_commands. This is a regression in Linux 2.6.15. Reported by Kristian Harms at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=187394 [ More complete commentary, as response to questions by Andrew: ] > This changes the call environment for all implementations of > ->Current_done(). Are they all safe to call under this lock? Short answer: Yes, trust me. ;-) Long answer: The done() callbacks are passed on to sbp2 from the SCSI stack along with each SCSI command via the queuecommand hook. The done() callback is safe to call in atomic context. So does Documentation/scsi/scsi_mid_low_api.txt say, and many if not all SCSI low-level handlers rely on this fact. So whatever this callback does, it is "self-contained" and it won't conflict with sbp2's internal ORB list handling. In particular, it won't race with the sbp2_command_orb_lock. Moreover, sbp2 already calls the done() handler with sbp2_command_orb_lock taken in sbp2scsi_complete_all_commands(). I admit this is ultimately no proof of correctness, especially since this portion of code introduced the spinlock recursion in the first place and we didn't realize it since this code's submission before 2.6.15 until now. (I have learned a lesson from this.) I stress-tested my patch on x86 uniprocessor with a preemptible SMP kernel (alas I have no SMP machine yet) and made sure that all code paths which involve the sbp2_command_orb_lock were gone through multiple times.

It doesn't make the splice itself necessarily nonblocking (because the actual file descriptors that are spliced from/to may block unless they have the O_NONBLOCK flag set), but it makes the splice pipe operations nonblocking. Signed-off-by: -

- msp3400c did not detect the second carrier, thus being always mono. - properly mute the msp3400c while detecting the carrier. - fix checks on the presence of scart2/3 inputs and scart 2 output. - implement proper audio mode fallbacks for msp3400c/d, identical to the way msp3400g works. - MODE_STEREO no longer produces dual languages when set for a bilingual transmission, instead it falls back to LANG1. Use LANG1_LANG2 to hear both languages of a bilingual transmission. This is much more intuitive for the user and is in accordance with the preferred usage in the v4l2 specification. - bttv tried to implement v4l2 calls with v4l1 calls to the i2c devices, completely mangling the audmode/rxsubchans handling. v4l2 calls now do v4l2 calls to the i2c devices. - fixed broken i2c_vidiocschan in bttv. - add start/end lines to LOG_STATUS.

Unfortunately on the budget-av board, the CAM reset line is tied to the frontend reset line, so resetting the CAM also zaps the frontend. This breaks the tda1004x at least, and causes it to fail to tune until the budget-av module is reloaded. This patch adds an exported function to dvb_frontend that allows a card to forcibly reinitialise a frontend. The budget-av now does this on CAM reset, which corrects this problem. since they do not tie the CAM reset line to the frontend reset line. Signed-off-by:

The dvr device could be opened multiple times simultaneously in O_RDONLY mode. Each open after the first would allocate a new dvr buffer (1880 KB) and leak the old buffer. The first close would de-allocate the dvr buffer and cause all other open dvrs to stop working. This patch allows only a single O_RDONLY open of the drv device, as per the API specification. Multiple O_WRONLY opens are still allowed and don't appear to cause any problems. Signed-off-by:
