62333e480d12ab186f89fe2725b372d12f72d5eb is the first bad commit commit 62333e480d12ab186f89fe2725b372d12f72d5eb Author: Jan Kara Date: Thu Jul 30 12:42:29 2026 +0200 udf: Fix data loss when converting inline inodes to out of line When udf_expand_file_adinicb() converts file from inline format to out of line, we use filemap_fdatawrite() to writeout the data to the new blocks. However since 36580ed08776 ("udf: Do not allocate blocks on page writeback") the writeback actually doesn't allocate the new block and the folio dirty bit is just silently cleared. Thus unless the file is written to after the conversion (as it can easily happen in case of truncate up), the data is just lost. Fix the problem by explicitely allocating the block underlying the data before starting writeback.
