* [PKT_SCHED] netem: allow random reordering (with fix)Stephen Hemminger2005-05-26
| | | | | | | | | | | | Here is a fixed up version of the reorder feature of netem. It is the same as the earlier patch plus with the bugfix from Julio merged in. Has expected backwards compatibility behaviour. Go ahead and merge this one, the TCP strangeness I was seeing was due to the reordering bug, and previous version of TSO patch.

|/ | | | | | | | | | | | | | | | | | | | | | | | In _spin_unlock_bh(lock): do { \ _raw_spin_unlock(lock); \ preempt_enable(); \ local_bh_enable(); \ __release(lock); \ } while (0) there is no reason for using preempt_enable() instead of a simple preempt_enable_no_resched() Since we know bottom halves are disabled, preempt_schedule() will always return at once (preempt_count!=0), and hence preempt_check_resched() is useless here... This fixes it by using "preempt_enable_no_resched()" instead of the "preempt_enable()", and thus avoids the useless preempt_check_resched() just before re-enabling bottom halves.

* [PATCH] Driver Core: remove driver model detach_stateDavid Brownell2005-05-17
| | | | | | | | | | | | | | | | The driver model has a "detach_state" mechanism that: - Has never been used by any in-kernel drive; - Is superfluous, since driver remove() methods can do the same thing; - Became buggy when the suspend() parameter changed semantics and type; - Could self-deadlock when called from certain suspend contexts; - Is effectively wasted documentation, object code, and headspace. This removes that "detach_state" mechanism; net code shrink, as well as a per-device saving in the driver model and sysfs.

* [PATCH] DAC960: add support for Mylex AcceleRAID 4/5/600Christoph Hellwig2005-05-05
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for a new class of DAC960 controllers. It's based on the GPLed idac320 driver from IBM for Linux 2.4.18. That driver is a fork of the 2.4.18 version of DAC960 that adds support for this new type of controllers (internally called "GEM Series"), that differ from other DAC960 V2 firmware controllers only in the register offsets and removes support for all others. This patch instead integrates support for these controllers into the DAC960 driver. Thanks to Anders Norrbring for pointing me to the idac320 driver and testing this patch. No Signed-Off: line because all code is either copy & pasted from IBM's idac320 driver or support for other controllers in the 2.6 DAC960 driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RTM_MAX is currently set to the maximum reserverd message type plus one thus being the cause of two bugs for new types being assigned a) given the new family registers only the NEW command in its reserved block the array size for per family entries is calculated one entry short and b) given the new family registers all commands RTM_MAX would point to the first entry of the block following this one and the rtnetlink receive path would accept a message type for a nonexisting family. This patch changes RTM_MAX to point to the maximum valid message type by aligning it to the start of the next block and subtracting one.

The documentation could be extended for more sources which are equipped by structured comments for recent 2.6 kernels. I have tried to proceed with that task. I have done that more times from 2.6.0 time and it gets boring to do same changes again and again. Linux kernel compiles after changes for i386 and ARM targets. I have added references to some more files into kernel-api book, I have added some section names as well. So please, check that changes do not break something and that categories are not too much skewed. I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved by kernel convention. Most of the other changes are modifications in the comments to make kernel-doc happy, accept some parameters description and do not bail out on errors. Changed <pid> to @pid in the description, moved some #ifdef before comments to correct function to comments bindings, etc. You can see result of the modified documentation build at http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz Some more sources are ready to be included into kernel-doc generated documentation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we only access reiserfs_key ->u.k_offset_v2 guts in four helper functions, we are free to sanitize those, as long as - layout of the structure is unchanged (it's on-disk object) - behaviour of these helpers is same as before. Patch kills the mess with endianness-dependent bitfields and replaces them with a single __le64. Helpers are switched to straightforward shift/and/or. Benefits: - exact same definitions for little- and big-endian architectures; no ifdefs in sight. - generate the same code on little-endian and improved on big-endian. - doesn't rely on lousy bitfields handling in gcc codegenerator. - happens to be standard C (unsigned long long is not a valid type for a bitfield; it's a gccism and not well-implemented one, at that).

At that point we are free to change layout of in_core_key - nothing depends on it anymore. So we drop the mess with union in there and simply use (unconditional) __u64 k_offset and __u8 k_type instead; places using in_core_key switched to those. That gives _far_ better code than current mess - on all platforms.

The reasons for adding this new function are: - some code currently testing _NSIG directly has off-by-one errors. Using this function instead avoids such errors. - some code currently tests unsigned signal numbers for <0 which is pointless and generates warnings when building with gcc -W. Using this function instead avoids such warnings. I considered various places to add this function but eventually settled on include/linux/signal.h as the most logical place for it. If there's some reason this is a bad choice then please let me know (hints as to a better location are then welcome of course).
