    [PATCH] fuse: clean up request size limit checking · 1d3d752b
    Miklos Szeredi authored
    Change the way a too large request is handled.  Until now in this case the
    device read returned -EINVAL and the operation returned -EIO.
    
    Make it more flexibible by not returning -EINVAL from the read, but restarting
    it instead.
    
    Also remove the fixed limit on setxattr data and let the filesystem provide as
    large a read buffer as it needs to handle the extended attribute data.
    
    The symbolic link length is already checked by VFS to be less than PATH_MAX,
    so the extra check against FUSE_SYMLINK_MAX is not needed.
    
    The check in fuse_create_open() against FUSE_NAME_MAX is not needed, since the
    dentry has already been looked up, and hence the name already checked.
