Subject: udf: Allocate name buffer in directory iterator on heap
commit 0aba4860b0d0216a1a300484ff536171894d49d8 upstream.
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.

Subject: udf: Avoid directory type conversion failure due to ENOMEM
commit df97f64dfa317a5485daf247b6c043a584ef95f9 upstream.
When converting directory from in-ICB to normal format, the last
iteration through the directory fixing up directory enteries can fail
due to ENOMEM. We do not expect this iteration to fail since the
directory is already verified to be correct and it is difficult to undo
the conversion at this point. So just use GFP_NOFAIL to make sure the
small allocation cannot fail.
