This unifies the set/clear/test bit functions of asm/bitops.h. I have not attempted to merge the bit-finding functions, since they rely on the machine word size and can't be easily restructured to work generically without a lot of #ifdefs. In particular, the 64-bit code can assume the presence of conditional move instructions, whereas 32-bit needs to be more careful. The inline assembly for the bit operations has been changed to remove explicit sizing hints on the instructions, so the assembler ...

So I've watched Linus' Google Tech Talk about git and let him convince me that I've been stupid to use CVS, that Subversion is even worse, and the only sensible approach is to use git. Went ahead and tried to convert my driver development to git. It didn't work too well. The first result was one of maximal embarrassment: I produced a patch that didn't even compile when applied to the official tree. This shouldn't happen with git, right? Well, it did. So now I'm back to keeping a virgin kernel sourc...

Greetings, Google is your friend. If you're looking for irc channels you can always try #git at irc.freenode.net Git howto/tutorial/... doesn't belong in the kernel mailinglist. Best wishes Kristoffer Ericson On Tue, 27 Nov 2007 23:33:21 +0100 -

It's git@vger.kernel.org. If you post there more specifics about what you tried and what the results were, they might be able to figure out what happened. Also, specifics about which documentation you read would help improve the docs. I believe that the in-tree beginner's documentation (the "tutorial" and the "user manual"--also the first hits for "git tutorial" and "git user manual" on google) explain how to do what you need, but perhaps it's not obvious where. --b. -

On Tue, 27 Nov 2007 15:22:56 -0800 (PST) I don't recall anyone ever demonstrating that prefetch is useful in-kernel. I think I've heard of situations where benefits have been seen in userspace - if a loop does a lot of calculation on each datum which it fetches then there's a good opportunity to pipeline the fetch with the on-core crunching. But kernel doesn't do that sort of thing.. -

I saw it in acpi when the __cpu_offset() pointers become zero. I have never seen it in vmstat.c. We do not need the vmstat.c fix. -

Jeff, I'm submitting a patch series for inclusion in 2.6.24 for the cxgb driver. The patches are built against Linus'git tree. Here is a brief description: - Ensure that GSO skbs have enough headroom before encapsulating them, - Fix a crash in NAPI mode, - Fix statistics accounting and report. Cheers, Divy -

Hello All, I am a linux application programmer and kernel newbie. I would like to use splice() / tee() to do some packet forwarding. I think these two systems calls are there in 2.6.18 kernel. My company is deciding to use either 2.6.21 or 2.6.22 kernel in our product. My question is : Is splice() stable in 2.6.21 / 2.6.22 ? I found this link where it says http://lwn.net/Articles/251707/ (search splice) Jens Axboe (2): splice: fix direct splice error handling Fix race with shared ...

[ This one needs to get into 2.6.24 ] With NO_HZ disabled, the UML idle loop effectively becomes a busy loop, as it will sleep for no time. The cause was forgetting to restart the tick after waking up from sleep. It was disabled before sleeping, and the remaining time used as the interval to sleep. So, the tick needs to be restarted when nanosleep finishes. This is done by introducing after_sleep_interval, which is empty in the NO_HZ case, but which sets the tick starting in the !NO_HZ case....
