From c5baa0edc4a70c2f44cb7422e2b47ab5c96570ed Mon Sep 17 00:00:00 2001 From: Krzysztof Halasa Date: Thu, 6 Jan 2011 16:23:01 +0100 Subject: Fix error handling with malloc, memalign etc. Introduce xmemalign(). MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The idea is to panic() when there is no memory available for normal operation. Exception: code which can consume arbitrary amount of RAM (example: files allocated in ramfs) must report error instead of panic(). This patch also fixes code which didn't check for NULL from malloc() etc. Usage: malloc(), memalign() return NULL when out of RAM. xmalloc(), xmemalign() always return non-NULL or panic().
