Here is another small OOM killer improvement. Previously we needed to reclaim SWAP_CLUSTER_MAX pages in a single pass. That should be changed so that we need only reclaim that many pages during the entire try_to_free_pages run, without going OOM. Signed-off-by:

1. typos/spelling ;-) 2. removed prev_vma and find_vma_prev because the condition checked later was always true 3. moved the free_area_cache/mmap_base check into arch_unmap_area_topdown where i think it belongs. 4. removed the extra free_area_cache setting code in the while loop as it only has to be set when we actually (and successfully) return from this function. The only visible change to the layout should be the following:

With silly pageout testcases it is possible to place huge amounts of memory under I/O. With a large request queue (CFQ uses 8192 requests) it is possible to place _all_ memory under I/O at the same time. This means that all memory is pinned and unreclaimable and the VM gets upset and goes oom. The patch limits the amount of memory which is under pageout writeout to be a little more than the amount of memory at which balance_dirty_pages() callers will synchronously throttle. This means that heavy pageout activity can starve heavy writeback activity completely, but heavy writeback activity will not cause starvation of pageout. Because we don't want a simple `dd' to be causing excessive latencies in page reclaim. Signed-off-by:

this patch fixes the problem, that the current kernel (linux-2.6.11-rc5) could not be compiled, when "support for early boot texts over serial port" (CONFIG_SERIAL_TEXT_DEBUG=y) is active. Signed-off-by:

`current' is a lousy choice for a variable name. This driver explodes on ppc64 because `current' expands to (local_paca->__current). OK, the driver doesn't compile on power4 anyway, but... Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by:

When I stat(2) a device node on a cramfs, the st_blocks field is bogus (it's derived from the size field which in this case holds the major/minor numbers). This makes du(1) output completely wrong. Signed-off-by:

We don't actually need this. The reason why the ppc64 build exploded was that I had CC="gcc -m64", and even though the build system turns that into "gcc -m64 -m32", that is, surprisingly, equivalent to "gcc -m64". Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by:

Here is a patch that replaces all occurrences of dst_pmtu in the TCP stack. As a result we no longer need ext2_header_len. This has a nice synergetic effect with Arnaldo's latest change to linux/tcp.h :) I'll be removing other users of dst->path/dst_pmtu next. Signed-off-by:

There is another bug in xfrm_bundle_ok where I forgot to check the validity of xdst->route. In fact, the check on dst->path isn't strong enough either. For IPv6 entries, dst->path->obsolete is always negative until you call ipv6_dst_check. So we really need to do that here. Here's the patch to fix those two problems. Yes I know my dst_check implementation is lame. I'll come back and fix up all the dst_check functions by moving their dst_release calls out. It proves that you were right in that IPv6 dst leak thread :) Signed-off-by:
