[PATCH v1 0/2] NFS: fix RCU and tracing pointer safety

Posted by Sean Chang 2 months, 1 week ago

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.

  NFS: use unsigned long for req field in nfs_page_class
