User-agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Thunderbird/109.0 
Updated patches attached.

The new output looks like:

  $ src/cp --debug src/cp file.sparse
  'src/cp' -> 'file.sparse'
  copy offload: yes, reflink: unsupported, sparse detection: no

  $ truncate -s+1M file.sparse

  $ src/cp --debug file.sparse file.sparse.cp
  'file.sparse' -> 'file.sparse.cp'
  copy offload: yes, reflink: unsupported, sparse detection: SEEK_HOLE

  $ src/cp --reflink=never --debug file.sparse file.sparse.cp
  'file.sparse' -> 'file.sparse.cp'
  copy offload: avoided, reflink: no, sparse detection: SEEK_HOLE


cheers,
Pádraig
