Hi all, I'd like to get your feedback on this: - Use kthread_run instead of doing a double-fork via kernel_thread() - Return proper error codes to user-space on failures Currently ipvsadm --start-daemon with an invalid --mcast-interface will silently suceed. With these changes we get an appropriate "No such device" error. - Use wait queues for both master and backup thread Instead of doing an endless loop with sleeping for one second, we now use wait queues. The master sync daemon ha...

Is the set_pages_* API that replaces change_page_attr described somewhere? I have been unable to find it with Google. I'm trying to modify the VirtualBox kernel module to work with 2.6.24-git (and 2.6.25) on x86_64 architecture. The current code has a value of the third argument of the call (prot) with 3 variants. All variations have the following bits set: _PAGE_PRESENT, _PAGE_RW, _PAGE_DIRTY, and _PAGE_ACCESSED. Number 2 adds _PAGE_NX to the above, and number 3 adds _PAGE_GLOBAL to the bits in ...

i think it might be better to just move the select to after the "config X86" option. (this is a legitimate use of select) Sam, do you concur? (but, your current fix should go in ASAP, so no objections from me.) Ingo --

Linus, while this is probably one of the last days of the merge window, please still consider pulling the "kgdb light" git tree from: git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-kgdb.git See the shortlog below. This is a slimmed-down and cleaned up version of KGDB that i've created out of the original patches that we submitted two weeks ago. I went over the kgdb patches with Thomas and we cut out everything that we did not like, and cleaned up the result. KGDB is ...

correct, this was a workaround which improved things for most people, but did not *fix* it. the real fix is to disable L1 ASPM alltogether at the cost of more power consumption, which is what is in e1000e in 2.6.25-git. Cheers, Auke --

no, from 2.6.25 onwards e1000e will support 82573 nics, so you'll have to migrate drivers, and you will get the fix automatically that way. after 2.6.25 releases, support for all pci-e nics will be removed from the e1000 driver. Cheers Auke --

just a few observations about the generated headers and whether there's some cleanup to be done there. 1) the generated header linux/tty.h consists solely of: ===== #ifndef _LINUX_TTY_H #define _LINUX_TTY_H /* * 'tty.h' defines some structures used by tty_io.c and some defines. */ #endif ===== i once submitted a patch that, if this header were included from userspace, would print, "Don't include me from user space, I'm empty." or something to that effect. is that worth d...

I finally had a bit of time to try out different kernel versions to find out where this began... and it's in 2.6.24-git2. What happens: Oracle 11g starts up and forks a number of so called background processes. Starting in 2.6.24-git2 the VKTM process never fully completes its initialization but gets in R state, never accumulating CPU, and can't be straced/gdb'd/killed. Sysrq-T reports for VKTM looks like this Feb 9 16:10:46 sandman kernel: ======================= Feb 9 16:10:46 sandma...

Hi all, [please to CC me] There's two things I want to comment on regarding menuconfig: 1) I know of the purpose of oldconfig, but I prefer using menuconfig for upgrading to newer kernel versions, because most of the time, I would select the standard options for new features anyway. menuconfig has the "(NEW)" string at the end of a feature's description. However, I find that hard to see among all the names of various lenghts. My proposal would be to have an "N" or a "NEW" appear to the _left...

rq->cmd[0] is never set to REQ_IDETAPE_READ_BUFFER so remove REQ_IDETAPE_READ_BUFFER handling from idetape_create_write_cmd() and the define itself. Then remove no longer used idetape_create_read_buffer_cmd() and IDETAPE_RETRIEVE_FAULTY_BLOCK define. There should be no functional changes caused by this patch.

There are 2 way of adding item to wait_queue, 1. add_wait_queue() 2. add_wait_queue_exclusive() and add_wait_queue_exclusive() is very useful API. unforunately, poll_wait_exclusive() against poll_wait() doesn't exist. it means there is no way that wake up only 1 process where polled. wake_up() is wake up all sleeping process by poll_wait(), not 1 process. this patch introduce poll_wait_exclusive() new API for allow wake up only 1 process. <usage example> unsigned int kosaki_poll(st...

Yo, Interesting patch series (I am being yuppie and reading this thread from my iPhone on a treadmill at the gym - so further comments later). I think that this is broadly along the lines that I was thinking, but this should be an RFC only patch series for now. Some initial questions: Where is the netlink interface? Polling an FD is so last century :) What testing have you done? Still, it is good to start with some code - eventually we might just have a full reservation API create...
