I'd probably replace the first sentence with something like this:

Since 204a575e91f3 "VFS: add common error checks to lookup_one_qstr_excl()"
filename_create() does not need to stash the error value from mnt_want_write()
into a separate variable - the logics that used to clobber 'error' after the
call of mnt_want_write() has migrated into lookup_one_qstr_excl().
