Hi,
I'm hoping to use rhashtable in lustre, to replace the resizeable
hashtable implementation in libcfs.
While working through the conversion I found some minor bugs in the
rhashtable code and documentation, and some areas where enhancements
could make rhashtable a better fit for lustre.
Fo
The documentation for rhashtable_walk_peek() wrong. It claims to
return the *next* entry, whereas it in fact returns the *previous*
entry.
However if no entries have yet been returned - or if the iterator
was reset due to a resize event, then rhashtable_walk_peek()
*does* return the next entry, bu
When a walk of the hashtable can be done entirely under RCU,
no objects will be missed - though seeing duplicates is possible.
This is because a cursor is kept in iter->p.
Without the cursor we depend on the ->skip counter. If an object
before the current location in hash chain is removed, the ->s
The documentation claims that when rhashtable_walk_start_check()
detects a resize event, it will rewind back to the beginning
of the table. This is not true. We need to set ->slot and
->skip to be zero for it to be true.

At the end of ip6_forward(), is there a good reason why
IPSTATS_MIB_OUTFORWDATAGRAMS and IPSTATS_MIB_OUTOCTETS are incremented
before the NF_HOOK? If the hook steals or drops the packet, this
counts still go up, which seems incorrect.
v4/ip_forward() increments these counters in ip_forward_finish

When we suspend and resume, we need to clear and re-enable the interrupt
scheme. This was previously not done while holding the RTNL lock, which
could be problematic, because we are actually destroying and re-creating
queues.

From: Jacob Keller
The iWarp client flags are all potentially changed when the RTNL lock is
not held, so they should not be part of the pf->flags variable. Instead,
move them into the state field so that we can use atomic bit operations.

Remove the gaps created by the recent refactor of various feature flags
that have moved to the state field. Use only a u32 now that we have
fewer than 32 flags in the field.

From: Björn Töpel
The driver now acts upon the XDP_REDIRECT return action. Two new ndos
are implemented, ndo_xdp_xmit and ndo_xdp_flush.
XDP_REDIRECT action enables XDP program to redirect frames to other

This flag is modified outside of the RTNL lock and thus should not be
part of the pf->flags variable.
Use a state bit instead, so that we can use atomic bit operations.

Now that the only places which modify flags are either (a) during
initialization prior to creating a netdevice, or (b) while holding the
rtnl lock, we no longer need the cmpxchg64 call in i40e_set_priv_flags.

This flag is modified during run time, possibly even when the RTNL lock
is not held. Additionally it has a few places which should be using
test_and_set or test_and_clear atomic bit operations.
Create a new state bit __I40E_UDP_SYNC_PENDING and use it instead of the
ole I40E_F
This series contains updates to i40e only.
Jake provides several patches which remove the need for cmpxchg64(),
starting with moving I40E_FLAG_[UDP]_FILTER_SYNC from pf->flags to pf->state

The two Flow Directory auto disable flags are used at run time to mark
when the flow director features needed to be disabled. Thus the flags
could change even when the RTNL lock is not held.
