Subject: [PATCH v1 0/2] NFS: fix RCU and tracing pointer safety
Date: Thu, 9 Apr 2026 00:14:26 +0800 [thread overview]
Message-ID: <20260408161428.155169-1-seanwascoding@gmail.com> (raw)
This series addresses two Sparse static analysis warnings in the NFS
client.
The first patch fixes an RCU-unsafe dereference when comparing
superblock addresses by adding the necessary RCU read lock and
dereference wrappers.
The second patch resolves a "noderef" warning in the tracing
infrastructure by changing a pointer field to an unsigned long,
ensuring we aren't incorrectly marking private trace-buffer
pointers as dereferenceable.
