* [PATCH] Fix swsusp with PNP BIOSOndrej Zary2006-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | swsusp is unable to suspend my machine (DTK FortisPro TOP-5A notebook) with kernel 2.6.17.5 because it's unable to suspend PNP device 00:16 (mouse). The problem is in PNP BIOS. pnp_bus_suspend() calls pnp_stop_dev() for the device if the device can be disabled according to pnp_can_disable(). The problem is that pnpbios_disable_resources() returns -EPERM if the device is not dynamic (!pnpbios_is_dynamic()) but insert_device() happily sets PNP_DISABLE capability/flag even if the device is not dynamic. So we try to disable non-dynamic devices which will fail. This patch prevents insert_device() from setting PNP_DISABLE if the device is not dynamic and fixes suspend on my system.

* [PATCH] inotify: fix deadlock found by lockdepArjan van de Ven2006-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a real deadlock, a nice complex one: (warning: long explanation follows so that Andrew can have a complete patch description) it's an ABCDA deadlock: A iprune_mutex B inode->inotify_mutex C ih->mutex D dev->ev_mutex The AB relationship comes straight from invalidate_inodes() int invalidate_inodes(struct super_block * sb) { int busy; LIST_HEAD(throw_away); mutex_lock(&iprune_mutex); spin_lock(&inode_lock); inotify_unmount_inodes(&sb->s_inodes); where inotify_umount_inodes() takes the mutex_lock(&inode->inotify_mutex); The BC relationship comes directly from inotify_find_update_watch(): s32 inotify_find_update_watch(struct inotify_handle *ih, struct inode *inode, u32 mask) { ... mutex_lock(&inode->inotify_mutex); mutex_lock(&ih->mutex); The CD relationship comes from inotify_rm_wd: inotify_rm_wd does mutex_lock(&inode->inotify_mutex); mutex_lock(&ih->mutex) and then calls inotify_remove_watch_locked() which calls notify_dev_queue_event() which does mutex_lock(&dev->ev_mutex); (this strictly is a BCD relationship) The DA relationship comes from the most interesting part: [<ffffffff8022d9f2>] shrink_icache_memory+0x42/0x270 [<ffffffff80240dc4>] shrink_slab+0x11d/0x1c9 [<ffffffff802b5104>] try_to_free_pages+0x187/0x244 [<ffffffff8020efed>] __alloc_pages+0x1cd/0x2e0 [<ffffffff8025e1f8>] cache_alloc_refill+0x3f8/0x821 [<ffffffff8020a5e5>] kmem_cache_alloc+0x85/0xcb [<ffffffff802db027>] kernel_event+0x2e/0x122 [<ffffffff8021d61c>] inotify_dev_queue_event+0xcc/0x140 inotify_dev_queue_event schedules a kernel_event which does a kmem_cache_alloc( , GFP_KERNEL) which may try to shrink slabs, including the inode cache .. which then takes iprune_mutex. And voila, there is an AB, a BC, a CD relationship (even a direct BCD), and also now a DA relationship -> a circular type AB-BA deadlock but involving 4 locks. The solution is simple: kernel_event() is NOT allowed to use GFP_KERNEL, but must use GFP_NOFS to not cause recursion into the VFS.

(TVR_BITS + i + 1 * TVN_BITS)) ... So this bugfix changes behaviour. It worked before by sheer luck: "If i was anything but 0, it was broken. But this was only used by s390 and arm. Since it was for the next interrupt, could that next interrupt be a problem (going into the second cascade)? But it was probably seldom wrong. That is, this would fail if the next interrupt was in the second cascade, and was wrapped. Which may never of happened. Also if it did happen, it would have just missed the interrupt. If an interrupt was missed, and no one was there to miss it, was it really missed :-)" Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Cc: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] panic_on_oops: remove ssleep()Horms2006-07-316-28/+14Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is part of an effort to unify the panic_on_oops behaviour across all architectures that implement it. It was pointed out to me by Andi Kleen that if an oops has occured in interrupt context, then calling sleep() in the oops path will only cause a panic, and that it would be really better for it not to be in the path at all. This patch removes the ssleep() call and reworks the console message accordinly. I have a slght concern that the resulting console message is too long, feedback welcome. For powerpc it also unifies the 32bit and 64bit behaviour. Fror x86_64, this patch only updates the console message, as ssleep() is already not present.

* [PATCH] knfsd: Fix stale file handle problem with subtree_checking.NeilBrown2006-07-311-7/+13
| | | | | | | | | | | | | | | | | | A recent commit (7fc90ec93a5eb71f4b08403baf5ba7176b3ec6b1) moved the call to nfsd_setuser out of the 'find a dentry for a filehandle' branch of fh_verify so that it would always be called. This had the unfortunately side-effect of moving *after* the call to decode_fh, so the prober fsuid was not set when nfsd_acceptable was called, the 'permission' check did the wrong thing. This patch moves the nfsd_setuser call back where it was, and add as call in the other branch of the if. Cc: "J.

| | | | | | | | | | | | | | | | The recent zlib update (commit 4f3865fb57a04db7cca068fed1c15badc064a302) broke ppc32 zImage decompression as it tries to decompress to address zero and the updated zlib_inflate checks that strm->next_out isn't a null pointer.

* [PATCH] delay accounting: temporarily enable by defaultShailabh Nagar2006-07-314-12/+14
| | | | | | | | | | | | | | | | Enable delay accounting by default so that feature gets coverage testing without requiring special measures. Earlier, it was off by default and had to be enabled via a boot time param. This patch reverses the default behaviour to improve coverage testing. It can be removed late in the kernel development cycle if its believed users shouldn't have to incur any cost if they don't want delay accounting. Or it can be retained forever if the utility of the stats is deemed common enough to warrant keeping the feature on.

* [PATCH] genirq: {en,dis}able_irq_wake() need refcounting tooDavid Brownell2006-07-312-2/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | IRQs need refcounting and a state flag to track whether the the IRQ should be enabled or disabled as a "normal IRQ" source after a series of calls to {en,dis}able_irq(). For shared IRQs, the IRQ must be enabled so long as at least one driver needs it active. Likewise, IRQs need the same support to track whether the IRQ should be enabled or disabled as a "wakeup event" source after a series of calls to {en,dis}able_irq_wake(). For shared IRQs, the IRQ must be enabled as a wakeup source during sleep so long as at least one driver needs it. But right now they _don't have_ that refcounting ... which means sharing a wakeup-capable IRQ can't work correctly in some configurations. This patch adds the refcount and flag mechanisms to set_irq_wake() -- which is what {en,dis}able_irq_wake() call -- and minimal documentation of what the irq wake mechanism does. Drivers relying on the older (broken) "toggle" semantics will trigger a warning; that'll be a handful of drivers on ARM systems.
