2006-03-11[PATCH] Wrong return value corrupts free object in e1000 driverDavid S. Miller1-1/+1
For some reason, E1000's ->hard_start_xmit() routine returns -EFAULT instead of one of the NETDEV_TX_* error codes. In fact, it frees up the SKB before returning this. This makes the queueing layer think the packet should be requeued and subsequently we corrupt a freed object. Signed-off-by: David S.

2006-03-11[PATCH] remove __put_task_struct_cb export againChristoph Hellwig3-9/+3
The patch '[PATCH] RCU signal handling' [1] added an export for __put_task_struct_cb, a put_task_struct helper newly introduced in that patch. But the put_task_struct couldn't be used modular previously as __put_task_struct wasn't exported. There are not callers of it in modular code, and it shouldn't be exported because we don't want drivers to hold references to task_structs. This patch removes the export and folds __put_task_struct into __put_task_struct_cb as there's no other caller.

Even though, we mount ext3 filesystem in writeback mode with "nobh" option, some one can do "chattr +j" on a single file to force it to do journalled mode.

2006-03-09[PATCH] slab: Node rotor for freeing alien caches and remote per cpu pages.Christoph Lameter3-14/+72
The cache reaper currently tries to free all alien caches and all remote per cpu pages in each pass of cache_reap. For a machines with large number of nodes (such as Altix) this may lead to sporadic delays of around ~10ms. Interrupts are disabled while reclaiming creating unacceptable delays. This patch changes that behavior by adding a per cpu reap_node variable. Instead of attempting to free all caches, we free only one alien cache and the per cpu pages from one remote node. That reduces the time spend in cache_reap. However, doing so will lengthen the time it takes to completely drain all remote per cpu pagesets and all alien caches. The time needed will grow with the number of nodes in the system. All caches are drained when they overflow their respective capacity. So the drawback here is only that a bit of memory may be wasted for awhile longer. Details: 1. Rename drain_remote_pages to drain_node_pages to allow the specification of the node to drain of pcp pages. 2. Add additional functions init_reap_node, next_reap_node for NUMA that manage a per cpu reap_node counter. 3. Add a reap_alien function that reaps only from the current reap_node. For us this seems to be a critical issue. Holdoffs of an average of ~7ms cause some HPC benchmarks to slow down significantly. F.e. NAS parallel slows down dramatically. NAS parallel has a 12-16 seconds runtime w/o rotor compared to 5.8 secs with the rotor patches. It gets down to 5.05 secs with the additional interrupt holdoff reductions.

2006-03-09[PATCH] s390: Increase spinlock retry code performanceChristian Ehrhardt1-2/+13
Currently the code tries up to spin_retry times to grab a lock using the cs instruction. The cs instruction has exclusive access to a memory region and therefore invalidates the appropiate cache line of all other cpus. If there is contention on a lock this leads to cache line trashing. This can be avoided if we first check wether a cs instruction is likely to succeed before the instruction gets actually executed.
