[PATCH] struct file leakage
2.6.16 leaks like hell. While testing, I found massive leakage (reproduced in openvz) in: *filp *size-4096 And 1 object leaks in *size-32 *size-64 *size-128 It is the fix for the first one. filp leaks in the bowels of namei.c. Seems, size-4096 is file table leaking in expand_fdtables. I have no idea what are the rest and why they show only accompanying another leaks. Some debugging structs?
