2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Kou Ishizaki commit 6747c2ee8abf749e63fee8cd01a9ee293e6a4247 upstream. A mutex_unlock(&gang->aff_mutex) in spufs_create_context() is missing in case spufs_context_open() fails. As a result, spu_create syscall and spu_get_idle() may block. This patch adds the mutex_unlock.
