if a driver returns an error in fill_read_buffer(), the buffer will be marked as filled. Subsequent reads will return eof. But there is no data because of an error, not because it has been read. Not marking the buffer filled is the obvious fix. Signed-off-by:

This patch prevents a race between IO and removing a file from sysfs. It introduces a list of sysfs_buffers associated with a file at the inode. Upon removal of a file the list is walked and the buffers marked orphaned. IO to orphaned buffers fails with -ENODEV. The driver can safely free associated data structures or be unloaded.

Don't stop on the first ->probe error that is not -ENODEV/-ENXIO. There might be a driver registered returning an unresonable return code, and this stops probing completely even though it may make sense to try the next possible driver. At worst, we may end up with an unbound device. Signed-off-by:

If we allow NULL as the new parent in device_move(), we need to make sure that the device is placed into the same place as it would if it was newly registered: - Consider the device virtual tree. In order to be able to reuse code, setup_parent() has been tweaked a bit. - kobject_move() can fall back to the kset's kobject. - sysfs_move_dir() uses the sysfs root dir as fallback. Signed-off-by:

Fix the key serial number collision avoidance code in key_alloc_serial(). This didn't use to be so much of a problem as the key serial numbers were allocated from a simple incremental counter, and it would have to go through two billion keys before it could possibly encounter a collision. However, now that random numbers are used instead, collisions are much more likely. This is fixed by finding a hole in the rbtree where the next unused serial number ought to be and using that by going almost back to the top of the insertion routine and redoing the insertion with the new serial number rather than trying to be clever and attempting to work out the insertion point pointer directly. This fixes kernel BZ #7727. Signed-off-by:
