2009-08-19ALSA: hda - Fix probe of Toshiba laptops with ALC268 codecTakashi Iwai
There are many variants of Toshiba laptops with ALC268 codec, and it seems that a few of them don't work with model=toshiba preset since they have the secondary ALC268 codec just for HDMI output. This is a regression due to the previous clean-up work to merge all Toshiba quirk entries into a single check. This patch adds the identification of such laptops to apply the standard BIOS-probing method. Unfortunately, Toshiba laptops have all the same PCI SSID, so we need to check the codec SSID to identify each device.

2009-08-18mm: build_zonelists(): move clear node_load[] to __build_all_zonelists()Bo Liu
If node_load[] is cleared everytime build_zonelists() is called,node_load[] will have no help to find the next node that should appear in the given node's fallback list. Because of the bug, zonelist's node_order is not calculated as expected. This bug affects on big machine, which has asynmetric node distance. [synmetric NUMA's node distance] 0 1 2 0 10 12 12 1 12 10 12 2 12 12 10 [asynmetric NUMA's node distance] 0 1 2 0 10 12 20 1 12 10 14 2 20 14 10 This (my bug) is very old but no one has reported this for a long time. Maybe because the number of asynmetric NUMA is very small and they use cpuset for customizing node memory allocation fallback.

2009-08-18mm: revert "oom: move oom_adj value"KOSAKI Motohiro
The commit 2ff05b2b (oom: move oom_adj value) moveed the oom_adj value to the mm_struct. It was a very good first step for sanitize OOM. However Paul Menage reported the commit makes regression to his job scheduler. Current OOM logic can kill OOM_DISABLED process. Why? His program has the code of similar to the following. ... set_oom_adj(OOM_DISABLE); /* The job scheduler never killed by oom */ ... if (vfork() == 0) { set_oom_adj(0); /* Invoked child can be killed */ execve("foo-bar-cmd"); } .... vfork() parent and child are shared the same mm_struct. then above set_oom_adj(0) doesn't only change oom_adj for vfork() child, it's also change oom_adj for vfork() parent. Then, vfork() parent (job scheduler) lost OOM immune and it was killed. Actually, fork-setting-exec idiom is very frequently used in userland program. We must not break this assumption. Then, this patch revert commit 2ff05b2b and related commit.

This turns out to be a bug brought by an -rc1 patch ("nilfs2: simplify remaining sget() use"). In the patch, a new "put resource" function, nilfs_put_sbinfo() was introduced to delay freeing nilfs_sb_info struct. But the nilfs_put_sbinfo() mistakenly used atomic_dec_and_test() function to check the reference count, and it caused the nilfs_sb_info was freed when user mounted a snapshot twice. This bug also suggests there was unseen memory leak in usual mount /umount operations for nilfs. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>

2009-08-18microblaze: Use klimit instead of _end for memory initMichal Simek
For noMMU system when you use larger rootfs image there is problem with using _end label because we increase klimit but in memory initialization we use still _end which is wrong. Larger mtd rootfs was rewritten by init_bootmem_node. MMU kernel use static initialization where klimit is setup to _end. There is no any other hanling with klimit.

2009-08-18microblaze: Sane handling of missing timer/intc in device treeJohn Williams
This code path doesn't test any returned pointers for NULL, leading to a bad kernel page fault if there's no timer/intc found. Slightly better is to BUG(), but even better still would be a printk beforehand. Signed-off-by: John Williams <john.williams@petalogix.com> Signed-off-by: Michal Simek <monstr@monstr.eu>

2009-08-18nilfs2: missing a read lock for segment writer in nilfs_attach_checkpoint()Zhang Qiang
'ns_cno' of structure 'the_nilfs' must be protected from segment writer, in other words, the caller of nilfs_get_checkpoint should hold read lock for nilfs->ns_segctor_sem. This patch adds the lock/unlock operations in nilfs_attach_checkpoint() when calling nilfs_cpfile_get_checkpoint().

2009-08-17net: restore gnet_stats_basic to previous definitionEric Dumazet
In 5e140dfc1fe87eae27846f193086724806b33c7d "net: reorder struct Qdisc for better SMP performance" the definition of struct gnet_stats_basic changed incompatibly, as copies of this struct are shipped to userland via netlink. Restoring old behavior is not welcome, for performance reason. Fix is to use a private structure for kernel, and teach gnet_stats_copy_basic() to convert from kernel to user land, using legacy structure (struct gnet_stats_basic) Based on a report and initial patch from Michael Spang.

2009-08-17NETROM: Fix use of static bufferRalf Baechle
The static variable used by nr_call_to_digi might result in corruption if multiple threads are trying to usee a node or neighbour via ioctl. Fixed by having the caller pass a structure in. This is safe because nr_add_node rsp. nr_add_neigh will allocate a permanent structure, if needed. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: David S.

2009-08-18Fix new incorrect error return from do_md_stop.NeilBrown
Recent commit c8c00a6915a2e3d10416e8bdd3138429beb96210 changed the exit paths in do_md_stop and was not quite careful enough. There is one path were 'err' now needs to be cleared but it isn't. So setting an array to readonly (with mdadm --readonly) will work, but will incorrectly report and error: ENXIO. Signed-off-by: NeilBrown <neilb@suse.de>

2009-08-17inotify: start watch descriptor count at 1Eric Paris
The inotify_add_watch man page specifies that inotify_add_watch() will return a non-negative integer. However, historically the inotify watches started at 1, not at 0. Turns out that the inotifywait program provided by the inotify-tools package doesn't properly handle a 0 watch descriptor. In 7e790dd5 we changed from starting at 1 to starting at 0. This patch starts at 1, just like in previous kernels, but also just like in previous kernels it's possible for it to wrap back to 0. This preserves the kernel functionality exactly like it was before the patch (neither method broke the spec) Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
