Subject: net: pegasus: Remove deprecated create_singlethread_workqueue
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=95ac3994514015823634ef1f7116dce24f26aa97;p=openwrt%2Fstaging%2Fblogic.git

net: pegasus: Remove deprecated create_singlethread_workqueue

The workqueue "pegasus_workqueue" queues a single work item per pegasus
instance and hence it doesn't require execution ordering. Hence,
alloc_workqueue has been used to replace the deprecated
create_singlethread_workqueue instance.

The WQ_MEM_RECLAIM flag has been set to ensure forward progress under
memory pressure since it's a network driver.

Since there are fixed number of work items, explicit concurrency
limit is unnecessary here.
