| | | | | | | | | | | | | | | | | | | | Instead of creating wmi_blocks and then register corresponding devices on a separate pass do it all in one shot, since lifetime rules for both objects are the same.

The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

* hp-wmi: Fix query interfaceMatthew Garrett2010-08-23
| | | | | | | | The machines I have appear to provide their return value in the arguments structure, not the output structure. Rework the driver to use that again in order to get rfkill working again. Signed-off-by: Matthew Garrett <mjg@redhat.com>
* ACPI_TOSHIBA needs LEDS supportJonathan Corbet2010-08-23
| | | | | | | | | | | | | | | | | | | | | Don't ask how ACPI_TOSHIBA got enabled on in desktop system's .config - I don't know. But it has silently been there until I tried 2.6.36-rc2, where it broke the build because I don't have LED support turned on. Attached patch fixes things up. (I had to change BACKLIGHT_CLASS_DEVICE to "depends" because otherwise I get unsightly core dumps out of scripts/kconfig/conf). jon -- toshiba: make sure we pull in LED support The Toshiba extras driver uses the LED module, so make sure we have it configure in.

* thinkpad-acpi: add support for model-specific keymapsHenrique de Moraes Holschuh2010-08-16
| | | | | | | | | | | Use the quirks engine to select model-specific keymaps, which makes it much easier to extend should we need it. Keycodes are based on the tables at http://www.thinkwiki.org/wiki/Default_meanings_of_special_keys.
