Subject: [PATCH 0/6] nfs_localio: fixes for races and errors from older compilers
Date: Wed, 30 Apr 2025 14:01:10 +1000 [thread overview]
Message-ID: <20250430040429.2743921-1-neil@brown.name> (raw)
Following the reports of older compilers complaining about the rcu
annotations in nfs-localio I reviewed the relevant code and found some
races and opportunities for simplification.
These patches address the various issues. They compile with old and new
versions of gcc and don't introduce new sprase warnings. I haven't
tested that localio, or even NFS, still work.
