Browse Source 
83bfe1485c build: add -Wthread-safety-pointer (fanquake)
240a4fb95d Squashed 'src/leveldb/' changes from 113db4962b..aba469ad6a (fanquake)

Pull request description:

  This will become available in Clang 21:

  > ThreadSafetyAnalysis now supports -Wthread-safety-pointer, which
  > enables warning on passing or returning pointers to guarded variables
  > as function arguments or return value respectively. Note that
  > ThreadSafetyAnalysis still does not perform alias analysis. The
  > feature will be default-enabled with -Wthread-safety in a future release.

  See https://github.com/llvm/llvm-project/blob/main/clang/docs/ReleaseNotes.rst.

  Also updates the leveldb subtree to pull: https://github.com/bitcoin-core/leveldb-subtree/pull/54.
