[ Upstream commit 0aba4860b0d0216a1a300484ff536171894d49d8 ]
Currently we allocate name buffer in directory iterators (struct udf_fileident_iter) on stack. These structures are relatively large (some 360 bytes on 64-bit architectures). For udf_rename() which needs to keep three of these structures in parallel the stack usage becomes rather heavy - 1536 bytes in total. Allocate the name buffer in the iterator from heap to avoid excessive stack usage.
