From 789e1e10f214c00ca18fc6610824c5b9876ba5f2 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Thu, 22 Dec 2022 09:51:30 -0500 Subject: nfsd: shut down the NFSv4 state objects before the filecache Currently, we shut down the filecache before trying to clean up the stateids that depend on it. This leads to the kernel trying to free an nfsd_file twice, and a refcount overput on the nf_mark. Change the shutdown procedure to tear down all of the stateids prior to shutting down the filecache.
