add __must_check to device management code

2006-09-26T04:08:39+00:00

We're getting a lot of crashes in the sysfs/kobject/device/bus/class code and they're very hard to diagnose. I'm suspecting that in some cases this is because drivers aren't checking return values and aren't handling errors correctly. So the code blithely blunders on and crashes later in very obscure ways. There's just no reason to ignore errors which can and do occur. So the patch sprinkles __must_check all over these APIs. Causes 1,513 new warnings. Heh.

PCI: docking station: remove dock uevents

2006-08-03T20:20:06+00:00

Remove uevent dock notifications. There are no consumers of these events at present, and uevents are likely not the correct way to send this type of event anyway. Until I get some kind of idea if anyone in userspace cares about dock events, I will just not send any. Signed-off-by: Kristen Carlson Accardi Signed-off-by: Greg Kroah-Hartman

KEVENT: add new uevent for dock

[PATCH] Driver Core: Add /sys/hypervisor when needed

2006-06-21T19:40:48+00:00

To have a home for all hypervisors, this patch creates /sys/hypervisor. A new config option SYS_HYPERVISOR is introduced, which should to be set by architecture dependent hypervisors (e.g. s390 or Xen). Acked-by: Martin Schwidefsky Signed-off-by: Michael Holzheu Signed-off-by: Greg Kroah-Hartman

[PATCH] sysfs: Allow sysfs attribute files to be pollable

2006-04-14T18:41:24+00:00

It works like this: Open the file Read all the contents. Call poll requesting POLLERR or POLLPRI (so select/exceptfds works) When poll returns, close the file and go to top of loop. or lseek to start of file and go back to the 'read'. Events are signaled by an object manager calling sysfs_notify(kobj, dir, attr); If the dir is non-NULL, it is used to find a subdirectory which contains the attribute (presumably created by sysfs_create_group). This has a cost of one int per attribute, one wait_queuehead per kobject, one int per open file. The name "sysfs_notify" may be confused with the inotify functionality. Maybe it would be nice to support inotify for sysfs attributes as well? This patch also uses sysfs_notify to allow /sys/block/md*/md/sync_action to be pollable Signed-off-by: Neil Brown Signed-off-by: Greg Kroah-Hartman

Revert mount/umount uevent removal

2006-02-22T17:39:02+00:00

This change reverts the 033b96fd30db52a710d97b06f87d16fc59fee0f1 commit from Kay Sievers that removed the mount/umount uevents from the kernel. Some older versions of HAL still depend on these events to detect when a new device has been mounted. These events are not correctly emitted, and are broken by design, and so, should not be relied upon by any future program. Instead, the /proc/mounts file should be polled to properly detect this kind of event. A feature-removal-schedule.txt entry has been added, noting when this interface will be removed from the kernel.
