From 77e69dac3cefacee939cb107ae9cd520a62338e0 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 1 Aug 2008 04:29:18 -0400 Subject: [PATCH] fix races and leaks in vfs_quota_on() users * new helper: vfs_quota_on_path(); equivalent of vfs_quota_on() sans the pathname resolution. * callers of vfs_quota_on() that do their own pathname resolution and checks based on it are switched to vfs_quota_on_path(); that way we avoid the races. * reiserfs leaked dentry/vfsmount references on several failure exits.
