Subject: [Qemu-devel] [PATCH 0/5] virtiofsd: multithreading preparation part 2
Date: Wed, 31 Jul 2019 17:10:01 +0100	[thread overview]
Message-ID: <20190731161006.9447-1-stefanha@redhat.com> (raw)

This is the second in a multi-series effort to make virtiofsd thread-safe.  The
main goal in this installment is to make lo_inode thread-safe, but other fixes
are included too.  Like any good author I will build suspense and won't tell
where this story is headed, but I still have some more code auditing to do
before we can declare virtiofsd thread-safe :).

Based-on: <20190726091103.23503-1-stefanha@redhat.com> ("virtiofsd: multithreading preparation")

Stefan Hajnoczi (5):
  virtiofsd: take lo->mutex around lo_add_fd_mapping()
  virtiofsd: take lo->mutex around lo_add_dirp_mapping()
  virtiofsd: rename inode->refcount to inode->nlookup
  virtiofsd: fix inode nlookup leaks
  virtiofsd: introduce inode refcount to prevent use-after-free
