-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.
