Subject: [PRE-REVIEW PATCH 11/16] treewide: Globally replace tasklet_init() by tasklet_setup()
This converts all remaining cases of the old tasklet_init() API into
tasklet_setup(), where the callback argument is the structure already
holding the struct tasklet_struct. These should have no behavioral changes,
since they just change which pointer is passed into the callback with
the same available pointers after conversion. Moreover, all callbacks
that were not passing a pointer of structure holding the struct
tasklet_struct has already been converted.
