alloc_workqueue replaces deprecated create_workqueue().
A dedicated workqueue has been used since the workqueue srp_remove_wq with
workitem &target->remove_work, is a work queue for the SRP target removal.
WQ_MEM_RECLAIM has been set to ensure forward progress under memory
pressure.
Since there are only a fixed number of work items, explicit
concurrency limit is unnecessary here.
Is the workqueue being used on a memory reclaim path?
Does it require WQ_MEM_RECLAIM?
Hello Bhaktipriya,
srp_remove_wq is used for SRP target port removal work only. This work
is neither queued from inside a shrinker nor by the page writeback code
so I think it is safe to drop WQ_MEM_RECLAIM.
Thanks,
Bart.
