[PATCH] [DLM] fix a couple of races

From: Satyam Sharma <[EMAIL PROTECTED]> Fix two races in fs/dlm/config.c: (1) Grab the configfs subsystem semaphore before calling config_group_find_obj() in get_space(). This solves a potential race between get_space() and concurrent mkdir(2) or rmdir(2). (2) Grab a reference on the found confi

[PATCH] DLM: fix a couple of races

Hi, There are the following two trivially-fixed races in fs/dlm/config.c: 1. The configfs subsystem semaphore must be held by the caller when calling config_group_find_obj(). It's needed to walk the subsystem hierarchy without racing with a simultaneous mkdir(2) or rmdir(2). I looked around t
