sysfs: remove s_sibling hacks
sysfs: remove s_sibling hacks
s_sibling was used for three different purposes:
1) as a linked list of entries in the directory
2) as a linked list of entries to be deleted
3) as a pointer to "struct completion"
This patch removes the hack and introduces new union u which
holds pointers for cases 2) and 3).
This change is needed for the following patch that removes s_sibling at all
and replaces it with a rb tree.
