2006-07-31[PATCH] documentation: Documentation/initrd.txtThomas Horsley
I spent a long time the other day trying to examine an initrd image on a fedora core 5 system because the initrd.txt file is apparently obsolete. Here is a patch which I hope will reduce future confusion for others.

2006-07-31[PATCH] vDSO hash-style fixRoland McGrath
The latest toolchains can produce a new ELF section in DSOs and dynamically-linked executables. The new section ".gnu.hash" replaces ".hash", and allows for more efficient runtime symbol lookups by the dynamic linker. The new ld option --hash-style={sysv|gnu|both} controls whether to produce the old ".hash", the new ".gnu.hash", or both. In some new systems such as Fedora Core 6, gcc by default passes --hash-style=gnu to the linker, so that a standard invocation of "gcc -shared" results in producing a DSO with only ".gnu.hash". The new ".gnu.hash" sections need to be dealt with the same way as ".hash" sections in all respects; only the dynamic linker cares about their contents. To work with older dynamic linkers (i.e. preexisting releases of glibc), a binary must have the old ".hash" section. The --hash-style=both option produces binaries that a new dynamic linker can use more efficiently, but an old dynamic linker can still handle. The new section runs afoul of the custom linker scripts used to build vDSO images for the kernel. On ia64, the failure mode for this is a boot-time panic because the vDSO's PT_IA_64_UNWIND segment winds up ill-formed. This patch addresses the problem in two ways. First, it mentions ".gnu.hash" in all the linker scripts alongside ".hash". This produces correct vDSO images with --hash-style=sysv (or old tools), with --hash-style=gnu, or with --hash-style=both. Second, it passes the --hash-style=sysv option when building the vDSO images, so that ".gnu.hash" is not actually produced. This is the most conservative choice for compatibility with any old userland. There is some concern that some ancient glibc builds (though not any known old production system) might choke on --hash-style=both binaries. The optimizations provided by the new style of hash section do not really matter for a DSO with a tiny number of symbols, as the vDSO has. If someone wants to use =gnu or =both for their vDSO builds and worry less about that compatibility, just change the option and the linker script changes will make any choice work fine.

2006-07-31[PATCH] delay accounting: temporarily enable by defaultShailabh Nagar
Enable delay accounting by default so that feature gets coverage testing without requiring special measures. Earlier, it was off by default and had to be enabled via a boot time param. This patch reverses the default behaviour to improve coverage testing. It can be removed late in the kernel development cycle if its believed users shouldn't have to incur any cost if they don't want delay accounting. Or it can be retained forever if the utility of the stats is deemed common enough to warrant keeping the feature on.

2006-07-14[PATCH] delay accounting taskstats interface send tgid onceShailabh Nagar
Send per-tgid data only once during exit of a thread group instead of once with each member thread exit. Currently, when a thread exits, besides its per-tid data, the per-tgid data of its thread group is also sent out, if its thread group is non-empty. The per-tgid data sent consists of the sum of per-tid stats for all *remaining* threads of the thread group. This patch modifies this sending in two ways: - the per-tgid data is sent only when the last thread of a thread group exits. This cuts down heavily on the overhead of sending/receiving per-tgid data, especially when other exploiters of the taskstats interface aren't interested in per-tgid stats - the semantics of the per-tgid data sent are changed. Instead of being the sum of per-tid data for remaining threads, the value now sent is the true total accumalated statistics for all threads that are/were part of the thread group. The patch also addresses a minor issue where failure of one accounting subsystem to fill in the taskstats structure was causing the send of taskstats to not be sent at all. The patch has been tested for stability and run cerberus for over 4 hours on an SMP.

2006-07-14[PATCH] per-task-delay-accounting: taskstats interfaceShailabh Nagar
Create a "taskstats" interface based on generic netlink (NETLINK_GENERIC family), for getting statistics of tasks and thread groups during their lifetime and when they exit. The interface is intended for use by multiple accounting packages though it is being created in the context of delay accounting. This patch creates the interface without populating the fields of the data that is sent to the user in response to a command or upon the exit of a task. Each accounting package interested in using taskstats has to provide an additional patch to add its stats to the common structure.

2006-07-10[PATCH] Fix and enable EDAC sysfs operationDoug Thompson
When EDAC was first introduced into the kernel it had a sysfs interface, but due to some problems it was disabled in 2.6.16 and remained disabled in 2.6.17. With feedback, several of the control and attribute files of that interface had some good constructive feedback. PCI Blacklist/Whitelist was a major set which has design issues and it has been removed in this patch. Instead of storing PCI broken parity status in EDAC, it has been moved to the pci_dev structure itself by a previous PCI patch. A future patch will enable that feature in EDAC by utilizing the pci_dev info. The sysfs is now enabled in this patch, with a minimal set of control and attribute files for examining EDAC state and for enabling/disabling the memory and PCI operations. The Documentation for EDAC has also been updated to reflect the new state of EDAC operation.

2006-07-03[PATCH] ZVC/zone_reclaim: Leave 1% of unmapped pagecache pages for file I/OChristoph Lameter
It turns out that it is advantageous to leave a small portion of unmapped file backed pages if all of a zone's pages (or almost all pages) are allocated and so the page allocator has to go off-node. This allows recently used file I/O buffers to stay on the node and reduces the times that zone reclaim is invoked if file I/O occurs when we run out of memory in a zone. The problem is that zone reclaim runs too frequently when the page cache is used for file I/O (read write and therefore unmapped pages!) alone and we have almost all pages of the zone allocated. Zone reclaim may remove 32 unmapped pages. File I/O will use these pages for the next read/write requests and the unmapped pages increase. After the zone has filled up again zone reclaim will remove it again after only 32 pages. This cycle is too inefficient and there are potentially too many zone reclaim cycles. With the 1% boundary we may still remove all unmapped pages for file I/O in zone reclaim pass. However. it will take a large number of read and writes to get back to 1% again where we trigger zone reclaim again. The zone reclaim 2.6.16/17 does not show this behavior because we have a 30 second timeout.

2006-07-02[PATCH] irq-flags: consolidate flags for request_irqThomas Gleixner
The recent interrupt rework introduced bit value conflicts with sparc. Instead of introducing new architecture flags mess, move the interrupt SA_ flags out of the signal namespace and replace them by interrupt related flags. This allows to remove the obsolete SA_INTERRUPT flag and clean up the bit field values. This patch: Move the interrupt related SA_ flags out of linux/signal.h and rename them to IRQF_ . This moves the interrupt related flags out of the signal namespace and allows to remove the architecture dependencies. SA_INTERRUPT is not needed by userspace and glibc so it can be removed safely. The existing SA_ constants are kept for easy transition and will be removed after a 6 month grace period.

2006-06-30[PATCH] pcmcia: expose tool in pcmcia/Documentation/pcmcia/Randy Dunlap
Expose example and tool source files in the Documentation/ directory in their own files instead of being buried (almost hidden) in readme/txt files. This will make them more visible/usable to users who may need to use them, to developers who may need to test with them, and to janitors who would update them if they were more visible. Also, if any of these possibly should not be in the kernel tree at all, it will be clearer that they are here and we can discuss if they should be removed.
