    fuse: update attributes on aio_read · a8894274

    A fuse-based network filesystem might allow for the inode
    and/or file data to change unexpectedly. A local client
    that opens and repeatedly reads a file might never pick
    up on such changes and indefinitely return stale data.
    
    Always invoke fuse_update_attributes() in the read path
    to cause an attr revalidation when the attributes expire.
    This leads to a page cache invalidation if necessary and
    ensures fuse issues new read requests to the fuse client.
    
    The original logic (reval only on reads beyond EOF) is
    preserved unless the client specifies FUSE_AUTO_INVAL_DATA
    on init.
