Several ioctl functions have the ability to call ice_get_rxfh, however
all of these ioctl functions do not provide all of the expected
information in ethtool_rxfh_param. For example, ethtool_get_rxfh_indir does
not provide an rss_key. This previously caused ethtool_get_rxfh_indir to
always fail with -EINVAL.
This change draws inspiration from i40e_get_rss to handle this
situation, by only calling the appropriate rss helpers when the
necessary information has been provided via ethtool_rxfh_param.
Fixes: b66a972abb6b ("ice: Refactor ice_set/get_rss into LUT and key specific functions")

Switch to use dev_err_probe() to simplify the error path and

message for -ENOMEM as allocator will print a big warning anyway
and remove duplicate message for devm_request_threaded_irq().

Currently nfs_mark_return_unreferenced_delegations marks all open but
not referenced delegations (i.e., those were found by a previous pass)
as return on close, which means that we'll return them on close without
a way out.
Replace this with only iterating delegations that are on the LRU list,
and avoid delegations that are in use by an open files to avoid this.
Delegations that were never referenced while open still are be prime
candidates for return from the LRU if the number of delegations is over
the watermark, or otherwise will be returned by the next
nfs_mark_return_unreferenced_delegations pass after they are closed.

Directly returning delegations on close when over the watermark is
rather suboptimal as these delegations are much more likely to be reused
than those that have been unused for a long time. Switch to returning
unused delegations from a new LRU list when we are above the threshold and
there are reclaimable delegations instead.
Pass over referenced delegations during the first pass to give delegations
that aren't in active used by frequently used for stat() or similar another
chance to not be instantly reclaimed. This scheme works the same as the
referenced flags in the VFS inode and dentry caches.

Searching for returnable delegations in the per-server delegations list
can be very expensive. While commit e04bbf6b1bbe ("NFS: Avoid quadratic
search when freeing delegations.") reduced the overhead a bit, the
fact that all the non-returnable delegations have to be searched limits
the amount of optimizations that can be done.
Fix this by introducing a separate list that only contains delegations
scheduled for return.

Currently most work on struct nfs_delegation happens directly under RCU
protection. This is generally fine, despite that long RCU sections are
not good for performance. But for operations later taking a reference
to the delegation to perform blocking work, refcount_inc is used, which
can be racy against dropping the last reference and thus lead to use
after frees in extremely rare cases.
Fix this by taking a reference in nfs4_get_valid_delegation using
refcount_inc_not_zero so that the callers have a stabilized reference
they can work with and can be moved outside the RCU critical section.

When nfs_detach_delegation_locked detaches a delegation from an inode,
it clears both nfsi->delegation and delegation->inode. Use the later
in update_open_stateid to check for a detached inode, as that avoids
an extra local variable, and removes the need for a RCU derefernence
as we already hold the lock in the delegation. This prepares for
removing the surrounding RCU critical section.
