    fuse: reject O_DIRECT flag also in fuse_create · 1b732396

    The comment in fuse_open about O_DIRECT:
      "VFS checks this, but only _after_ ->open()"
    also holds for fuse_create, however, the same kind of check was missing there.
    As an impact of this bug, open(newfile, O_RDWR|O_CREAT|O_DIRECT) fails, but a
    stub newfile will remain if the fuse server handled the implied FUSE_CREATE
    request appropriately.
    Other impact: in the above situation ima_file_free() will complain to open/free
    imbalance if CONFIG_IMA is set.
