[PATCH 0/6] Assorted rhashtable improvements. RESEND

[[ I mistyped linux-kernel the first time I sent these, so resending. Please reply to this set. Sorry - neilb ]] Some of these have been posted before and a couple received an Ack from Herbert, but haven't appeared in any git tree yet. Another (the first) has been sent but received no ack.

[PATCH 3/6] rhashtable: reset iter when rhashtable_walk_start sees new table

[PATCH 6/6] rhashtable: add rhashtable_walk_prev()

rhashtable_walk_prev() returns the object returned by the previous rhashtable_walk_next(), providing it is still in the table (or was during this grace period). This works even if rhashtable_walk_stop() and rhashtable_talk_start() have been called since the last rhashtable_walk_next(). If there

[PATCH 4/6] rhashtable: improve rhashtable_walk stability when stop/start used.

When a walk of an rhashtable is interrupted with rhastable_walk_stop() and then rhashtable_walk_start(), the location to restart from is based on a 'skip' count in the current hash chain, and this can be incorrect if insertions or deletions have happened. This does not happen when the walk is not
