[Xen-devel] [PATCH] xenstore: Fix deadlock in xs_read_watch

[Daniel De Graaf <dgdegra@xxxxxxxxxxxxx>]

When read_message returns -1 while a read is pending, an attempt is made
to lock h->request_mutex which is already locked by the reader. Change
the read thread to only exit on thread cancellation, where
read_thr_exists will return 0.
