Inotify watch removals suck violently. To kick the watch out we need (in this order) inode->inotify_mutex and ih->mutex. That's fine if we have a hold on inode; however, for all other cases we need to make damn sure we don't race with umount. We can *NOT* just grab a reference to a watch - inotify_unmount_inodes() will happily sail past it and we'll end with reference to inode potentially outliving its superblock. Ideally we just want to grab an active reference to superblock if we can; that will make sure we won't go into inotify_umount_inodes() until we are done. Cleanup is just deactivate_super(). However, that leaves a messy case - what if we *are* racing with umount() and active references to superblock can't be acquired anymore? We can bump ->s_count, grab ->s_umount, which will almost certainly wait until the superblock is shut down and the watch in question is pining for fjords. That's fine, but there is a problem - we might have hit the window between ->s_active getting to 0 / ->s_count - below S_BIAS (i.e. the moment when superblock is past the point of no return and is heading for shutdown) and the moment when deactivate_super() acquires ->s_umount. We could just do drop_super() yield() and retry, but that's rather antisocial and this stuff is luser-triggerable. OTOH, having grabbed ->s_umount and having found that we'd got there first (i.e. that ->s_root is non-NULL) we know that we won't race with inotify_umount_inodes(). So we could grab a reference to watch and do the rest as above, just with drop_super() instead of deactivate_super(), right? Wrong. We had to drop ih->mutex before we could grab ->s_umount. So the watch could've been gone already. That still can be dealt with - we need to save watch->wd, do idr_find() and compare its result with our pointer. If they match, we either have the damn thing still alive or we'd lost not one but two races at once, the watch had been killed and a new one got created with the same ->wd at the same address. That couldn't have happened in inotify_destroy(), but inotify_rm_wd() could run into that. Still, "new one got created" is not a problem - we have every right to kill it or leave it alone, whatever's more convenient. So we can use idr_find(...) == watch && watch->inode->i_sb == sb as "grab it and kill it" check. If it's been our original watch, we are fine, if it's a newcomer - nevermind, just pretend that we'd won the race and kill the fscker anyway; we are safe since we know that its superblock won't be going away. And yes, this is far beyond mere "not very pretty"; so's the entire concept of inotify to start with.

A common reason for device drivers to implement their own printk macros is the lack of a printk prefix with the standard pr_xyz macros. Introduce a pr_fmt() macro that is applied for every pr_xyz macro to the format string. The most common use of the pr_fmt macro would be to add the name of the device driver to all pr_xyz messages in a source file.

This reverts commit e51af663, which was wrongly hoovered up and submitted about a month after a better fix had already been merged. The better fix is commit cbda1ba8 ("PCI/iommu: blacklist DMAR on Intel G31/G33 chipsets"), where we do this blacklisting based on the DMI identification for the offending motherboard, since sometimes this chipset (or at least a chipset with the same PCI ID) apparently _does_ actually have an IOMMU.

Currently libata uses four methods to detect device presence. 1. PHY status if available. 2. TF register R/W test (only promotes presence, never demotes) 3. device signature after reset 4. IDENTIFY failure detection in SFF state machine Combination of the above works well in most cases but recently there have been a few reports where a phantom device causes unnecessary delay during probe. In both cases, PHY status wasn't available. In one case, it passed #2 and #3 and failed IDENTIFY with ATA_ERR which didn't qualify as #4. The other failed #2 but as it passed #3 and #4, it still caused failure. In both cases, phantom device reported diagnostic failure, so these cases can be safely worked around by considering any !ATA_DRQ IDENTIFY failure as NODEV_HINT if diagnostic failure is set.

With CONFIG_IRQSOFF_TRACER the trace_hardirqs_off() function includes a call to __builtin_return_address(1). But we calltrace_hardirqs_off() from early entry code. There we have just a single stack frame. So this results in a kernel stack backchain walk that would walk beyond the kernel stack. Following the NULL terminated backchain this results in a lowcore read access. To fix this we simply call trace_hardirqs_off_caller() and pass the current instruction pointer.

This bug were supposed to be fixed by 5ba2f67a, where a call to NULL happens. Not all tvaudio chips allow controlling bass/treble. So, the driver has a table with a flag to indicate if the chip does support it. Unfortunately, the handling of this logic were broken for a very long time (probably since the first module version). Due to that, an OOPS were generated for devices that don't support bass/treble. This were the resulting OOPS message before the patch, with debug messages enabled: tvaudio' 1-005b: VIDIOC_S_CTRL BUG: unable to handle kernel NULL pointer dereference at 00000000 IP: [<00000000>] *pde = 22fda067 *pte = 00000000 Oops: 0000 [#1] SMP Modules linked in: snd_hda_intel snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss snd_mixer_oss snd_pcm snd_timer snd_hwdep snd soundcore tuner_simple tuner_types tea5767 tuner tvaudio bttv bridgebnep rfcomm l2cap bluetooth it87 hwmon_vid hwmon fuse sunrpc ipt_REJECT nf_conntrack_ipv4 iptable_filter ip_tables ip6t_REJECT xt_tcpudp nf_conntrack_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables x_tables ipv6 dm_mirrordm_multipath dm_mod configfs videodev v4l1_compat ir_common 8139cp compat_ioctl32 v4l2_common 8139too videobuf_dma_sg videobuf_core mii btcx_risc tveeprom i915 button snd_page_alloc serio_raw drm pcspkr i2c_algo_bit i2c_i801 i2c_core iTCO_wdt iTCO_vendor_support sr_mod cdrom sg ata_generic pata_acpi ata_piix libata sd_mod scsi_mod ext3 jbdmbcache uhci_hcd ohci_hcd ehci_hcd [last unloaded: soundcore] Pid: 15413, comm: qv4l2 Not tainted (2.6.25.14-108.fc9.i686 #1) EIP: 0060:[<00000000>] EFLAGS: 00210246 CPU: 0 EIP is at 0x0 EAX: 00008000 EBX: ebd21600 ECX: e2fd9ec4 EDX: 00200046 ESI: f8c0f0c4 EDI: f8c0f0c4 EBP: e2fd9d50 ESP: e2fd9d2c DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process qv4l2 (pid: 15413, ti=e2fd9000 task=ebe44000 task.ti=e2fd9000) Stack: f8c0c6ae e2ff2a00 00000d00 e2fd9ec4 ebc4e000 e2fd9d5c f8c0c448 00000000 f899c12a e2fd9d5c f899c154 e2fd9d68 e2fd9d80 c0560185 e2fd9d88 f8f3e1d8 f8f3e1dc ebc4e034 f8f3e18c e2fd9ec4 00000000 e2fd9d90 f899c286 c008561c Call Trace: [<f8c0c6ae>] ? chip_command+0x266/0x4b6 [tvaudio] [<f8c0c448>] ? chip_command+0x0/0x4b6 [tvaudio] [<f899c12a>] ? i2c_cmd+0x0/0x2f [i2c_core] [<f899c154>] ? i2c_cmd+0x2a/0x2f [i2c_core] [<c0560185>] ? device_for_each_child+0x21/0x49 [<f899c286>] ? i2c_clients_command+0x1c/0x1e [i2c_core] [<f8f283d8>] ? bttv_call_i2c_clients+0x14/0x16 [bttv] [<f8f23601>] ? bttv_s_ctrl+0x1bc/0x313 [bttv] [<f8f23445>] ? bttv_s_ctrl+0x0/0x313 [bttv] [<f8b6096d>] ? __video_do_ioctl+0x1f84/0x3726 [videodev] [<c05abb4e>] ? sock_aio_write+0x100/0x10d [<c041b23e>] ? kmap_atomic_prot+0x1dd/0x1df [<c043a0c9>] ? enqueue_hrtimer+0xc2/0xcd [<c04f4fa4>] ? copy_from_user+0x39/0x121 [<f8b622b9>] ? __video_ioctl2+0x1aa/0x24a [videodev] [<c04054fd>] ? do_notify_resume+0x768/0x795 [<c043c0f7>] ? getnstimeofday+0x34/0xd1 [<c0437b77>] ? autoremove_wake_function+0x0/0x33 [<f8b62368>] ? video_ioctl2+0xf/0x13 [videodev] [<c048c6f0>] ? vfs_ioctl+0x50/0x69 [<c048c942>] ? do_vfs_ioctl+0x239/0x24c [<c048c995>] ? sys_ioctl+0x40/0x5b [<c0405bf2>] ? syscall_call+0x7/0xb [<c0620000>] ? cpuid4_cache_sysfs_exit+0x3d/0x69 ======================= Code: Bad EIP value.

This patch checks for volume, bass, treble, set mode and get mode callbacks before actually enabling the code that would use them. Instead of aborting the driver for load, this patch will allow it to load with a reduced number of functionatities. This prevents OOPS if some board entry is missing a needed callback.

generic_checkmode() were called, via a callback, for some tvaudio chips. There's just one callback code used on all those boards. So, it makes no sense on keeping this as a callback. Since there were some OOPS reported on tvaudio on kerneloops.org, this patch removes this callback, adding the code at the only place were it is called: inside chip_tread. A flag were added to indicate the need for a kernel thread to set stereo mode on cards that needs it. Using this more direct approach simplifies the code, making it more robust against human errors.
