From 35e874b1d5d56dd2098313364b879c637fa56844 Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Fri, 25 Oct 2013 08:47:35 +0100 Subject: [PATCH] libxenstore: Use PTHREAD_STACK_MIN The existing value of 16K is smaller than the arm64 minimum stack size, which is 128K. PTHREAD_STACK_MIN appears to be standard http://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_attr_setstacksize.html Consindered setting a lower bound but the stack requirements of the watcher thread are pretty minimal (tens of bytes from the looks of it) and unlikely to blow PTHREAD_STACK_MIN on any useful platform.
