But I think that probably is the best way to go. I'd suggest that passing in iocb rather than file is the way to go. Most callers of ->write_begin already pass NULL as the first argument so would not need to change. i915/gem passes a non-NULL file, but it only operates on shmem and shmem does not use the file argument, so they can pass NULL instead. fs/buffer.c simply passes through the file passed to write_begin and can be changed to pass through the iocb passed in. exfat_extend_valid_size() has an iocb in its caller and can pass in the iocb instead. generic_perform_write() has an iocb.
