Subject: __d_move(): fold manipulations with ->d_child/->d_subdirs
X-Git-Tag: fixes-for-v3.18-merge-window~58^2~5

__d_move(): fold manipulations with ->d_child/->d_subdirs

list_del() + list_add() is a slightly pessimised list_move()
list_del() + INIT_LIST_HEAD() is a slightly pessimised list_del_init()

Interleaving those makes the resulting code even worse.  And harder to follow...
