From c27db314b8f32b9bf4c3c6ce72edb16a25a7f4b8 Mon Sep 17 00:00:00 2001 From: Raghavendra Bhat Date: Mon, 10 Oct 2011 16:25:46 +0530 Subject: libglusterfs/syncop: do not rely on synctask set in makecontext Across glibc implementations, interpretation of argc/argv passed to makecontext() is different. This patch does away with dependence on such arguments passed to makecontext(). Instead,synctask reference is retrieved from pthread_getspecific().
