-stable review patch. If anyone has any objections, please let us know. ------------------ From: Kirill Korotaev When found, it is obvious. nfds calculated when allocating fdsets is rewritten by calculation of size of fdtable, and when we are unlucky, we try to free fdsets of wrong size. Found due to OpenVZ resource management (User Beancounters).
