These are safe. Recent 2.2.x kernels include a patch from andrea that
makes copy_from/to_user much more likely to schedule. Whoever coded
reiserfs_file_write correctly realized it was possible for these calls
to schedule (and correctly dealt with it), but before they almost never
did schedule, so the debugging was probably forgotten.
