From 31fc366aa7aa911ebc0744e99c82caee4e97315a Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 16 Dec 2024 20:40:59 +0000 Subject: netfs: Drop the was_async arg from netfs_read_subreq_terminated() Drop the was_async argument from netfs_read_subreq_terminated(). Almost every caller is either in process context and passes false. Some filesystems delegate the call to a workqueue to avoid doing the work in their network message queue parsing thread. The only exception is netfs_cache_read_terminated() which handles completion in the cache - which is usually a callback from the backing filesystem in softirq context, though it can be from process context if an error occurred. In this case, delegate to a workqueue.
