+Subject: [PATCH] fix compile failure with libc musl
+
+The lack of random_r in musl:
+[snip]
+|main.c:1393:7: warning: implicit declaration of function 'random_r';
+did you mean 'random'? [-Wimplicit-function-declaration]
+|  rv = random_r(&rand_data, &val);
+|       ^~~~~~~~
+|       random
+|main.c:1408:30: error: invalid application of 'sizeof' to incomplete
+type 'struct random_data'
+|  memset(&rand_data, 0, sizeof(rand_data));
+[snip]
+
+s/random_r/random/, s/initstate_r/initstate/ and remove `static struct
+random_data rand_data'
+
+Here is the man of `random_r()':
+[snip]
+The random_r() function is like random(3), except that instead of using
+state information maintained in a global variable
+[snip]
+
+So use random without state information is OK.

+SUMMARY = "A shared storage lock manager"
+DESCRIPTION = "sanlock  is  a lock manager built on shared storage.  Hosts with access \
+to the storage can perform locking.   An  application  running  on  the \
+hosts  is  given  a small amount of space on the shared block device or \
+file, and uses sanlock for its  own  application-specific  synchronization. \
+Internally,  the  sanlock  daemon manages locks using two disk-based \
+lease algorithms: delta leases and paxos leases."
