| | | | | | | | | | This reverts commit 8b249b6856f16f09b0e5b79ce5f4d435e439b9d6. This 'fix' is not necessary; we just need to undo the damage caused accidentally by Igor/Mauro in 4b29631db33292d416dc395c56122ea865e7635c ("V4L/DVB (9533): cx88: Add support for TurboSight TBS8910 DVB-S PCI card") Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

| * md/raid1 - don't assume newly allocated bvecs are initialised.NeilBrown2009-04-061-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit d3f761104b097738932afcc310fbbbbfb007ef92 newly allocated bvecs aren't initialised to NULL, so we have to be more careful about freeing a bio which only managed to get a few pages allocated to it. Otherwise the resync process crashes. This patch is appropriate for 2.6.29-stable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It appears I inadvertly introduced rq->lock recursion to the hrtimer_start() path when I delegated running already expired timers to softirq context. This patch fixes it by introducing a __hrtimer_start_range_ns() method that will not use raise_softirq_irqoff() but __raise_softirq_irqoff() which avoids the wakeup. It then also changes schedule() to check for pending softirqs and do the wakeup then, I'm not quite sure I like this last bit, nor am I convinced its really needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When kmemtrace was ported to ftrace, the marker strings were taken as an indication of how the traced data was being exposed to the userspace. However, the actual format had been binary, not text. This restores the original binary format, while also adding an origin CPU field (since ftrace doesn't expose the data per-CPU to userspace), and re-adding the timestamp field. It also drops arch-independent field sizing where it didn't make sense, so pointers won't always be 64 bits wide like they used to.

This problem gets masked in practice because most fs.h using sites use rcupreempt.h (and other headers) which includes percpu.h which brings in asm/page.h indirectly. We cannot add asm/page.h to asm/fs.h because page.h is not an exported header. Move simple_transaction_set() to the other simple-transaction file helpers in fs/libfs.c. This removes the include file hell and also reduces kernel size a bit.

In practice most fs.h using .c files get gfp.h included implicitly, via an indirect route: via rcupdate.h inclusion - so this underlying problem gets masked in practice. So we want to solve fs.h's dependency on gfp.h. gfp.h can not be included here directly because it is not exported and it would break the build the following way: /home/mingo/tip/usr/include/linux/bsg.h:11: found __[us]{8,16,32,64} type without #include <linux/types.h> /home/mingo/tip/usr/include/linux/fs.h:11: included file 'linux/gfp.h' is not exported make[3]: *** [/home/mingo/tip/usr/include/linux/.check] Error 1 make[2]: *** [linux] Error 2 As suggested by Alexey Dobriyan, move alloc_secdata() and free_secdata() to linux/security.h - they belong there. This also cleans fs.h of GFP_* usage.
