Hmm, I need to discuss with Miklos if there is any interest to merge my
DIO consolidation branch - it needs to be heavily updated and my main
motivation to have the shared inode lock for for O_DIRECT writes is not
possible. But it merges fuse_direct_write_iter (FOPEN_DIRECT_IO) and
fuse_cache_write_iter into one call path (and actually fixes some
FOPEN_DIRECT_IO xfstests failures). For that branch I need to have
file_remove_privs separated.

As I said, it need discussion if there is interest for that branch.

For current code, looks good to me.
