sysfs: use file mode defines from stat.h

2013-07-16T17:57:37Z

With the last patches stat.h was included to the header, and thus those permission defines should be used. Signed-off-by: Oliver Schinagl Signed-off-by: Greg Kroah-Hartman

sysfs: add more helper macro's for (bin_)attribute(_groups)

2013-07-16T17:57:37Z

With the recent changes to sysfs there's various helper macro's. However there's no RW, RO BIN_ helper macro's. This patch adds them. Signed-off-by: Oliver Schinagl Signed-off-by: Greg Kroah-Hartman

sysfs: add support for binary attributes in groups

2013-07-16T17:57:36Z

groups should be able to support binary attributes, just like it supports "normal" attributes. This lets us only handle one type of structure, groups, throughout the driver core and subsystems, making binary attributes a "full fledged" part of the driver model, and not something just "tacked on".

sysfs.h: add BIN_ATTR macro

2013-07-16T17:57:36Z

This makes it easier to create static binary attributes, which is needed in a number of drivers, instead of "open coding" them. Reviewed-by: Guenter Roeck Tested-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

sysfs.h: add ATTRIBUTE_GROUPS() macro

2013-07-16T17:57:36Z

To make it easier for driver subsystems to work with attribute groups, create the ATTRIBUTE_GROUPS macro to remove some of the repetitive typing for the most common use for attribute groups. Reviewed-by: Guenter Roeck Tested-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

sysfs.h: add __ATTR_RW() macro

2013-07-16T17:57:36Z

A number of parts of the kernel created their own version of this, might as well have the sysfs core provide it instead. Reviewed-by: Guenter Roeck Tested-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

sysfs: Functions for adding/removing symlinks to/from attribute groups

2013-01-25T20:51:13Z

The most convenient way to expose ACPI power resources lists of a device is to put symbolic links to sysfs directories representing those resources into special attribute groups in the device's sysfs directory. For this purpose, it is necessary to be able to add symbolic links to attribute groups. For this reason, add sysfs helper functions for adding/removing symbolic links to/from attribute groups, sysfs_add_link_to_group() and sysfs_remove_link_from_group(), respectively. This change set includes a build fix from David Rientjes. Signed-off-by: Rafael J. Wysocki Acked-by: Greg Kroah-Hartman

sysfs: get rid of some lockdep false positives

2012-05-14T19:19:56Z

This patch (as1554) fixes a lockdep false-positive report. The problem arises because lockdep is unable to deal with the tree-structured locks created by the device core and sysfs. This particular problem involves a sysfs attribute method that unregisters itself, not from the device it was called for, but from a descendant device. Lockdep doesn't understand the distinction and reports a possible deadlock, even though the operation is safe. This is the sort of thing that would normally be handled by using a nested lock annotation; unfortunately it's not feasible to do that here. There's no sensible way to tell sysfs when attribute removal occurs in the context of a parent attribute method. As a workaround, the patch adds a new flag to struct attribute telling sysfs not to inform lockdep when it acquires a readlock on a sysfs_dirent instance for the attribute. The readlock is still acquired, but lockdep doesn't know about it and hence does not complain about impossible deadlock scenarios. Also added are macros for static initialization of attribute structures with the ignore_lockdep flag set. The three offending attributes in the USB subsystem are converted to use the new macros.
