2008-07-20V4L/DVB (7949): videodev: renamed the vidioc_*_fmt_* callbacksHans Verkuil17-310/+302
The naming for the callbacks that handle the VIDIOC_ENUM_FMT and VIDIOC_S/G/TRY_FMT ioctls was very confusing. Renamed it to match the v4l2_buf_type name. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-07-20V4L/DVB (7939): pvrusb2: Remove sysfs interface hackeryMike Isely1-346/+114
Back in the early days of the pvrusb2 driver, the kernel class mechanism in use for the sysfs interface had no means to pass per-attribute information to the show / store functions. This forced me to implement a horrible ugly thunking mechanism (i.e. infer the missing data through the use of dedicated cookie cutter bounce functions). However now we're using a better mechanism which also passes enough additional information to the show / store functions that we no longer need the hack. So eliminate all the crap. Yay!

2008-07-20V4L/DVB (7938): pvrusb2: Increase enforced encoder wait delay to improve ↵Mike Isely1-2/+4
reliability The driver enforces a "quiet period" on the encoder in certain situations before attempting to operate it. This seems to help avoid video encoding errors / corruption. The quiet period was 50msec, but through experimentation it has been observed to improve further if the interval is increased to 100msec.

2008-07-20V4L/DVB (7883): pvrusb2: make default frequency configurable via modprobe optionMichael Krufky1-4/+12
The pvrusb2 driver initially sets the tuner to known broadcast frequencies in the Chicago area, to ease driver testing for the maintainer. This patch keeps those default frequencies, but allows them to be altered via modprobe option. This allows the same ease and convenience for testing multiple pvrusb2 devices one after another under other conditions and areas. For instance, the default initial frequency, 175.25 MHz, might not necessarily be valid on all cable television networks, but usually will be a valid NTSC broadcast channel.

2008-07-17ftrace: do not trace library functionsIngo Molnar1-12/+5
make function tracing more robust: do not trace library functions. We've already got a sizable list of exceptions: ifdef CONFIG_FTRACE # Do not profile string.o, since it may be used in early boot or vdso CFLAGS_REMOVE_string.o = -pg # Also do not profile any debug utilities CFLAGS_REMOVE_spinlock_debug.o = -pg CFLAGS_REMOVE_list_debug.o = -pg CFLAGS_REMOVE_debugobjects.o = -pg CFLAGS_REMOVE_find_next_bit.o = -pg CFLAGS_REMOVE_cpumask.o = -pg CFLAGS_REMOVE_bitmap.o = -pg endif ... and the pattern has been that random library functionality showed up in ftrace's critical path (outside of its recursion check), causing hard to debug lockups. So be a bit defensive about it and exclude all lib/*.o functions by default. It's not that they are overly interesting for tracing purposes anyway. Specific ones can still be traced, in an opt-in manner. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-07-16fix dangling zombie when new parent ignores childrenRoland McGrath1-0/+26
This fixes an arcane bug that we think was a regression introduced by commit b2b2cbc4b2a2f389442549399a993a8306420baf. When a parent ignores SIGCHLD (or uses SA_NOCLDWAIT), its children would self-reap but they don't if it's using ptrace on them. When the parent thread later exits and ceases to ptrace a child but leaves other live threads in the parent's thread group, any zombie children are left dangling. The fix makes them self-reap then, as they would have done earlier if ptrace had not been in use. Signed-off-by: Roland McGrath <roland@redhat.com>
