A recent change introduced a type cast from a private 64-bit
value to a pointer, which works fine on 64-bit architectures,
but not on 32-bit ones, where it produces a harmless compiler
warning:
fs/btrfs/extent_io.c: In function 'btrfs_free_io_failure_record':
fs/btrfs/extent_io.c:2193:13: warning: cast to pointer from integer of
different size [-Wint-to-pointer-cast]
This adds an intermediate cast to 'unsigned long', which tells
the compiler to ignore the type mismatch.

or when the inode is freeing")
