2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-08[NET]: user of the jiffies rounding code: NetworkingArjan van de Ven
This patch introduces users of the round_jiffies() function in the networking code. These timers all were of the "about once a second" or "about once every X seconds" variety and several showed up in the "what wakes the cpu up" profiles that the tickless patches provide. Some timers are highly dynamic based on network load; but even on low activity systems they still show up so the rounding is done only in cases of low activity, allowing higher frequency timers in the high activity case. The various hardware watchdogs are an obvious case; they run every 2 seconds but aren't otherwise specific of exactly when they need to run.

2006-08-09[NET]: add_timer -> mod_timer() in dst_run_gc()Dmitry Mishin
Patch from Dmitry Mishin <dim@openvz.org>: Replace add_timer() by mod_timer() in dst_run_gc in order to avoid BUG message. CPU1 CPU2 dst_run_gc() entered dst_run_gc() entered spin_lock(&dst_lock) ..... del_timer(&dst_gc_timer) fail to get lock .... mod_timer() <--- puts timer back to the list add_timer(&dst_gc_timer) <--- BUG because timer is in list already. Found during OpenVZ internal testing. At first we thought that it is OpenVZ specific as we added dst_run_gc(0) call in dst_dev_event(), but as Alexey pointed to me it is possible to trigger this condition in mainstream kernel. F.e. timer has fired on CPU2, but the handler was preeempted by an irq before dst_lock is tried. Meanwhile, someone on CPU1 adds an entry to gc list and starts the timer. If CPU2 was preempted long enough, this timer can expire simultaneously with resuming timer handler on CPU1, arriving exactly to the situation described.

2005-07-30[NET] Fix too aggressive backoff in dst garbage collectionDenis Lunev
The bug is evident when it is seen once. dst gc timer was backed off, when gc queue is not empty. But this means that timer quickly backs off, if at least one destination remains in use. Normally, the bug is invisible, because adding new dst entry to queue cancels the backoff. But it shots deadly with destination cache overflow when new destinations are not released for long time f.e. after an interface goes down. The fix is to cancel backoff when something was released.

2005-04-16[PATCH] Fix dst_destroy() raceHerbert Xu
When we are not the real parent of the dst (e.g., when we're xfrm_dst and the child is an rtentry), it may already be on the GC list. In fact the current code is buggy to, we need to check dst->flags before the dec as dst may no longer be valid afterwards.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
