| block layer: increase size of disk stat counters | Ben Woodard | Thu, 09 Mar 2006 21:04:49 -0800 | 2 files changed, 9 insertions(+), 9 deletions(-) | 1891 Bytes |
The kernel's representation of the disk statistics uses the type unsigned which is 32b on both 32b and 64b platforms. Unfortunately, most system tools that work with these numbers that are exported in /proc/diskstats including iostat read these numbers into unsigned longs. This works fine on 32b platforms and when the number of IO transactions are small on 64b platforms. However, when the numbers wrap on 64b platforms & you read the numbers into unsigned longs, and compare the numbers to previous readings, then you get an unsigned representation of a negative number. This looks like a very large 64b number & gives you bizarre readouts in iostat:ilc4: Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s rkB/s wkB/s avgrq-sz avgqu-sz await svctm %utilThough fixing iostat in user space is possible, and a quick survey indicates that several other similar tools also use unsigned longs when processing /proc/diskstats. Therefore, it seems like a better approach would be to extend the length of the disk_stats structure on 64b architectures to 64b. The following patch does that. It should not affect the operation on 32b platforms. Signed-off-by: Ben Woodard <woodard@redhat.com> Signed-off-by: Andrew Morton <akpm@osdl.org> |

EDAC is still causing a few problems and the code is relatively green. Mark it as experimental until thing settle down. Also, provide some documentation pointers in Kconfig help.

| Add full driver model support for the IPMI driver. It links in the proper bus and device support. It adds an "ipmi" driver interface that has each BMC discovered by the driver (as a device). These BMCs appear in the devices/platform directory. If there are multiple interfaces to the same BMC, the driver should discover this and will only have one BMC entry. The BMC entry will have pointers to each interface device that connects to it. The device information (statistics and config information) has not yet been ported over to the driver model from proc, that will come later. This work was based on work by Yani Ioannou. I basically rewrote it using that code as a guide, but he still deserves credit :). Need to increment the version number because of the new PCI and sysfs capabilities of the driver. People maintaining things for distros have asked that I do this after interface or major functional changes.

| This patchset provides the basic infrastructure for user-space probes based on IBM's Dprobes. Similar to kprobes, user-space probes uses the breakpoint mechanism to insert probes. User has to write a kernel module to insert probes in the executable/library and specify the handlers in the kernel module. Using this mechanism user can not only log user-space data structure present in the memory when probe was hit, but also log kernel data structures, stack traces, system registers etc. User-space tools like systemtap can use this interface to probe applications and libraries. Design and development of this user-space probe mechanism has been discussed in systemtap mailing lists. Features supported: 1. Probes on application executable. 2. Probes on libraries. 3. Probes are visible across fork(). 4. Probes can be inserted even on executables/libraries that are not even started running(pages not present in memory). 5. Multiple handlers can be inserted/removed for each probe. Signed-off-by: Prasanna S Panchamukhi <prasanna@in.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> |

| We need to allow that different stripes are of different effective sizes, and use the appropriate size. Also, when a stripe is being expanded, we must block any IO attempts until the stripe is stable again. Key elements in this change are: - each stripe_head gets a 'disk' field which is part of the key, thus there can sometimes be two stripe heads of the same area of the array, but covering different numbers of devices. One of these will be marked STRIPE_EXPANDING and so won't accept new requests. - conf->expand_progress tracks how the expansion is progressing and is used to determine whether the target part of the array has been expanded yet or not.

Stack-Corruption detector patch attached. But implementing the stack corruption detector was alot harder than i anticipated. It works the following way: It poisons the kernel stack more or less intelligently (by tracking esp changes and by not poisoning the stack on every call), but it still has to check the whole kernel stack for every function call. I was able to successfully boot on a testbox, and the detector immediately triggered when i provoked a kernel stack corruption somewhere in the middle of the kernel stack. (do "gettimeofday(3, 3)" to get the same kernel stack corruption.)

NOTE: Bootup will be _very_ slow (we check the integrity of the kernel stack for _every_ function call), so be patient - the kernel is not hung. It should boot within 20-30 minutes on your laptop though (it booted in ~3 minutes on a 2GHz box - which boots under 1 minute normally).

| This adds hotplug memory support to UML. The mconsole syntax is config mem=[+-]n[KMG] In other words, add or subtract some number of kilobytes, megabytes, or gigabytes. Unplugged pages are allocated and then madvise(MADV_REMOVE), which is a currently experimental madvise extension. These pages are tracked so they can be plugged back in later if the admin decides to give them back. The first page to be unplugged is used to keep track of about 4M of other pages. A list_head is the first thing on this page. The rest is filled with addresses of other unplugged pages. This first page is not madvised, obviously. When this page is filled, the next page is used in a similar way and linked onto a list with the first page. Etc. This whole process reverses when pages are plugged back in. When a tracking page no longer tracks any unplugged pages, then it is next in line for plugging, which is done by freeing pages back to the kernel. This patch also removes checking for /dev/anon on the host, which is obsoleted by MADVISE_REMOVE. Signed-off-by: Jeff Dike <jdike@addtoit.com> Signed-off-by: Andrew Morton <akpm@osdl.org> |
