quiesce: bring in feature to re-transmit the frames
there was a corner case of 'fops' failing if they were in transit during a disconnection, if the failure is due to 'ENOTCONN' re-transmit the frame. Signed-off-by: Amar Tumballi <amar@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 1500 (Mount point should not be in-accessible between reconnect to server) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=1500
