* hwmon: (w83781d) Drop W83627HF supportJean Delvare2008-02-071-12/+6
| | | | | | | | | | The W83627HF hardware monitoring features are supported by the w83627hf driver for several years now. Support by the w83781d has been advertised as deprecated 6 months ago, it's about time to see it go. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M.

* hwmon: (lm78/w83781d) Probe fewer I2C addressesJean Delvare2008-02-072-5/+5
| | | | | | | | | We've never seen any device supported by the lm78 or w83781d driver at addresses 0x20-0x27, so let's stop probing these addresses. Extra probes cost time, and have potential for confusing or misdetecting other I2C devices. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>

The driver will report the reason of the last wake up in the sysfs attribute "wakeup_reason": 0 for "none, unknown, or standard ACPI wake up event", 1 for "bay ejection request" and 2 for "undock request". The firmware will also report if the operation that triggered the wake up has been completed, by issuing an HKEY 0x3003 or 0x4003 event. If the operation fails, no event is sent. When such a hotunplug sucessfull notification is issued, the driver sets the attribute "wakeup_hotunplug_complete" to 1. While the firmware does tell us whether we are waking from a suspend or hibernation scenario, the Linux way of hibernating makes this information not reliable, and therefore it is not reported. The idea is that if any of these attributes are non-zero, userspace might want to do something at the end of the "wake up from sleep" procedures, such as offering to send the machine back into sleep as soon as it is safe to do so.

For these models, one has to poll the CMOS NVRAM to check the key state at a rate faster than the expected rate at which the user might repeatedly press the same hot key. This patch implements this functionality for many of the hotkeys in a transparent way: hot keys will now Just Work, and the driver knows the best approach (events or NVRAM polling) to employ, based on the HKEY.MHKA ACPI method. Also, the driver can turn off the polling when there are no users for the hot keys that need such polling. The NVRAM-based hot keys of the A3x series that have never been implemented by later models are not supported, to avoid changes in the keymap of the input devices that could cause headaches in the future. There is a Kconfig option to avoid compiling the NVRAM polling code, as it is not very small, and unlikely to be useful on any ThinkPad newer than a T40, X31 or R52. This feature is based on a previous effort by Richard Hughes.

Furthermore, this removes the temptation to use iget() to find an inode by number in a filesystem from code outside that filesystem. iget_locked() should be used instead. A new function is added in an earlier patch (iget_failed) that is to be called to mark an inode as bad, unlock it and release it should the get routine fail. Mark iget() and read_inode() as being obsolete and remove references to them from the documentation. Typically a filesystem will be modified such that the read_inode function becomes an internal iget function, for example the following: void thingyfs_read_inode(struct inode *inode) { ... } would be changed into something like: struct inode *thingyfs_iget(struct super_block *sp, unsigned long ino) { struct inode *inode; int ret; inode = iget_locked(sb, ino); if (!inode) return ERR_PTR(-ENOMEM); if (!(inode->i_state & I_NEW)) return inode; ... unlock_new_inode(inode); return inode; error: iget_failed(inode); return ERR_PTR(ret); } and then thingyfs_iget() would be called rather than iget(), for example: ret = -EINVAL; inode = iget(sb, ino); if (!inode || is_bad_inode(inode)) goto error; becomes: inode = thingyfs_iget(sb, ino); if (IS_ERR(inode)) { ret = PTR_ERR(inode); goto error; } Note that is_bad_inode() does not need to be called. The error returned by thingyfs_iget() should render it unnecessary.

Information includes pid, uid, tgid, vm size, rss, cpu, oom_adj score, and name. This is helpful for determining why there was an OOM condition and which rogue task caused it. It is configurable so that large systems, such as those with several thousand tasks, do not incur a performance penalty associated with dumping data they may not desire. If an OOM was triggered as a result of a memory controller, the tasklist shall be filtered to exclude tasks that are not a member of the same cgroup.

This allows control file reads and writes to access their subsystem state without having to be concerned with locking against cgroup destruction - the control file dentry will keep the cgroup and its subsystem state objects alive until the file is closed. The documentation is updated to reflect the changed semantics of destroy(); additionally the locking comments for destroy() and some other methods were clarified and decrustified.
