3.13.11-ckt38 -stable review patch. If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Nikolay Borisov <kernel@xxxxxxxx> commit ab73ef46398e2c0159f3a71de834586422d2a44a upstream. When dqget() in __dquot_initialize() fails e.g. due to IO error, __dquot_initialize() will pass an array of uninitialized pointers to dqput_all() and thus can lead to deference of random data. Fix the problem by properly initializing the array.
