27 ***************** !!! IMPORTANT NOTE FOR BACKEND CODERS !!! *****************
29 * The SIPE core assumes atomicity and is *NOT* thread-safe.
31 * It *does not* protect any of its data structures or code paths with locks!
33 * In no circumstances it must be interrupted by another thread calling
34 * sipe_core_xxx() while the first thread has entered the SIPE core through
35 * a sipe_core_xxx() function.
