+Subject: [PATCH] random: Fix hang of _gcry_rndjent_get_version.
+
+* random/rndjent.c (_gcry_rndjent_get_version): Move locking.
+
+--
+
+While the protection for jent_rng_collector is needed,
+_gcry_rndjent_poll is also acquiring the lock for the variable.
+Thus, it hangs.
+
+This change is sub-optimal, the lock is once released after the call
+of _gcry_rndjent_poll.  It might be good to modify the API of
+_gcry_rndjent_poll to explicitly allow this use case of forcing
+initialization keeping the lock.
+
+Comments and change log entry by gniibe.
