3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Michael Halcrow <mhalcrow@xxxxxxxxxx> commit 942080643bce061c3dd9d5718d3b745dcb39a8bc upstream. Dmitry Chernenkov used KASAN to discover that eCryptfs writes past the end of the allocated buffer during encrypted filename decoding. This fix corrects the issue by getting rid of the unnecessary 0 write when the current bit offset is 2.
