In graph_setup function glfs_subvol_done is called which is executed in an epoll thread. glfs_lock waits on other thread to finish graph migration. This can lead to dead lock if we consume all the epoll threads. In general any call-back function executed in epoll thread should not call any blocking call which waits on a network reply either directly or indirectly, e.g. syncop functions should not be called in these threads. As a fix we should not wait for migration in the call-back path.
