From a2ea9a9072607c2fd6442bd1ffb4dbdbf882aed7 Mon Sep 17 00:00:00 2001 From: David Howells Date: Wed, 4 Dec 2024 07:47:01 +0000 Subject: rxrpc: Use irq-disabling spinlocks between app and I/O thread Where a spinlock is used by both the application thread and the I/O thread, use irq-disabling locking so that an interrupt taken on the app thread doesn't also slow down the I/O thread.
