  rxrpc: Use alloc_ordered_workqueue() to create ordered workqueues (2023-05-25 12:15:36 -1000)

workqueue: Ordered workqueue creation cleanups

For historical reasons, unbound workqueues with max concurrency limit of 1
are considered ordered, even though the concurrency limit hasn't been
system-wide for a long time. This creates ambiguity around whether ordered
execution is actually required for correctness, which was actually confusing
for e.g. btrfs (btrfs updates are being routed through the btrfs tree).

There aren't that many users in the tree which use the combination and there
are pending improvements to unbound workqueue affinity handling which will
make inadvertent use of ordered workqueue a bigger loss. This pull request
clarifies the situation for most of them by updating the ones which require
ordered execution to use alloc_ordered_workqueue().

There are some conversions being routed through subsystem-specific trees and
likely a few stragglers. Once they're all converted, workqueue can trigger a
warning on unbound + @max_active==1 usages and eventually drop the implicit
ordered behavior.
