+autofs-5.1.7 - use default stack size for threads
+
+From: Ian Kent <raven@themaw.net>
+
+autofs uses PTHREAD_STACK_MIN to set the stack size for threads it
+creates.
+
+In two cases it is used to reduce the stack size for long running
+service threads while it's used to allocate a larger stack for worker
+threads that can have larger memory requirements.
+
+In recent glibc releases PTHREAD_STACK_MIN is no longer a constant
+which can lead to unexpectedly different stack sizes on different
+architectures and the autofs assumption it's a constant causes a
+compile failure.
+
+The need to alter the stack size was due to observed stack overflow
+which was thought to be due the thread stack being too small for autofs
+and glibc alloca(3) usage.
+
+Quite a bit of that alloca(3) usage has been eliminated from autofs now,
+particularly those that might be allocating largish amounts of storage,
+and there has been a lot of change in glibc too so using the thread
+default stack should be ok.
