[PATCH 0/26] sysfs cleanups v3.

Here is the third respin of my sysfs patches.

Tejun had a good point I was doing to much when I touched __sysfs_read_dir.
So that work has been split into 3 patches.

This made a good excuse for me to review the if (!dir_sd) check and be
certain it was not needed. I have not found any actual problems so
the resulting code is the same as the last patchset.

Now the change to delete each dirent in sysfs_read_dir is it's own
separate patch so Tejun can happily beat me up on just that one idea.
I honestly can't see how holding sysfs_mutex over the entire directory
deletion helps anything.

The net change is less buggy than the current sysfs and a fair bit simpler.
