[PATCH 0/3] mm: tmpfs radix_tree swap leftovers

[Hugh Dickins]

Here's three miscellaneous patches on top of the tmpfs radix_tree swap
work in 3.0-rc6-mm1: an overdue unrelated cleanup in radix_tree_tag_get(),
an unfortunately necessary speedup to tmpfs swapoff, and an attempt to
address your review feedback on the exceptional cases in filemap.c.

1/3 radix_tree: clean away saw_unset_tag leftovers
2/3 tmpfs radix_tree: locate_item to speed up swapoff
3/3 mm: clarify the radix_tree exceptional cases
