* [PATCH] blk: fix merge bug in as-ioschedTejun Heo2005-10-291-0/+1
| | | | | | | | | | | | | | | | | as-iosched deals with aliased requests differently from other ioscheds. It links together aliased requests using rq->queuelist instead of spilling alises to dispatch queue like other ioscheds do. Requests linked in this way cannot be merged. Unfortunately, generic q->last_merge handling patch didn't take this into account and q->last_merge could be set to an aliased request resulting in Badness, corrupt list and eventually panic. This explicitly marks aliased requests to be unmergeable. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

The test can be unnecessarily long (and occurs while holding the tasklist_lock). Especially long on a large system with thousands of active tasks. The ptrace caller (presumably a debugger) specifies the pid of its target and an address to peek or poke. But the debugger could be attached to several tasks. The idea of find_thread_for_addr() is to find whether the target address is in the RBS for any of those tasks. Currently it searches the thread-list of the target pid. If that search does not find a match, and the shared mm-struct's user count indicates that there are other tasks sharing this address space (a rare occurrence), a search is made of all the tasks in the system. Another approach can drastically shorten this procedure. It depends upon the fact that in order to peek or poke from/to any task, the debugger must first attach to that task. And when it does, the attached task is made a child of the debugger (is chained to its children list). Therefore we can search just the debugger's children list.

| | | * | | [IA64] - Avoid slow TLB purges on SGI Altix systemsDean Roe2005-10-273-20/+29
| | | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | flush_tlb_all() can be a scaling issue on large SGI Altix systems since it uses the global call_lock and always executes on all cpus. When a process enters flush_tlb_range() to purge TLBs for another process, it is possible to avoid flush_tlb_all() and instead allow sn2_global_tlb_purge() to purge TLBs only where necessary. This patch modifies flush_tlb_range() so that this case can be handled by platform TLB purge functions and updates ia64_global_tlb_purge() accordingly. sn2_global_tlb_purge() now calculates the region register value from the mm argument introduced with this patch.
