device_schedule_callback() needs a module reference

2007-04-27T17:57:32+00:00

This patch (as896b) fixes an oversight in the design of device_schedule_callback(). It is necessary to acquire a reference to the module owning the callback routine, to prevent the module from being unloaded before the callback can run.

Since d9a9cdfb078d755e648d53ec25b7370f84ee5729 is using ENOSYS without including if CONFIG_SYSFS is disabled. Fixed by including . Signed-off-by: Ralf Baechle Signed-off-by: Linus Torvalds

[PATCH] sysfs and driver core: add callback helper, used by SCSI and S390

2007-03-15T22:29:26+00:00

This patch (as868) adds a helper routine for device drivers that need to set up a callback to perform some action in a different process's context. This is intended for use by attribute methods that want to unregister themselves or their parent device. Attribute method calls are mutually exclusive with unregistration, so such actions cannot be taken directly. Two attribute methods are converted to use the new helper routine: one for SCSI device deletion and one for System/390 ccwgroup devices.

sysfs: allow attributes to be added to groups

2007-02-23T23:03:46+00:00

This patch (as860) adds two new sysfs routines: sysfs_add_file_to_group() and sysfs_remove_file_from_group(). A later patch adds code that uses the new routines. Signed-off-by: Alan Stern Cc: Maneesh Soni Signed-off-by: Greg Kroah-Hartman

sysfs: move struct sysfs_dirent to private header

2007-02-23T22:52:09+00:00

struct sysfs_dirent is private to the fs/sysfs/ subtree. It is not even referenced as an opaque structure outside of that subtree. The following patch moves the declaration from include/linux/sysfs.h to fs/sysfs/sysfs.h, making it clearer that nothing else in the kernel dereferences it. I have been running this patch for years. Please integrate and forward upstream if there are no objections. From: "Adam J. Richter" Signed-off-by: Greg Kroah-Hartman

sysfs: Shadow directory support

2007-02-07T18:37:14+00:00

The problem. When implementing a network namespace I need to be able to have multiple network devices with the same name. Currently this is a problem for /sys/class/net/*. What I want is a separate /sys/class/net directory in sysfs for each network namespace, and I want to name each of them /sys/class/net. I looked and the VFS actually allows that. All that is needed is for /sys/class/net to implement a follow link method to redirect lookups to the real directory you want. Implementing a follow link method that is sensitive to the current network namespace turns out to be 3 lines of code so it looks like a clean approach. Modifying sysfs so it doesn't get in my was is a bit trickier. I am calling the concept of multiple directories all at the same path in the filesystem shadow directories. With the directory entry really at that location the shadow master. The following patch modifies sysfs so it can handle a directory structure slightly different from the kobject tree so I can implement the shadow directories for handling /sys/class/net/.

SYSFS: Fix missing include of list.h in sysfs.h

Sysfs.h uses definitions (e.g. struct list_head s_sibling) from list.h but does not include it. Signed-off-by: Frank Haverkamp Signed-off-by: Greg Kroah-Hartman

driver core: Introduce device_move(): move a device to a new parent.

2006-12-01T22:52:01+00:00

Provide a function device_move() to move a device to a new parent device. Add auxilliary functions kobject_move() and sysfs_move_dir(). kobject_move() generates a new uevent of type KOBJ_MOVE, containing the previous path (DEVPATH_OLD) in addition to the usual values. For this, a new interface kobject_uevent_env() is created that allows to add further environmental data to the uevent at the kobject layer.
