The bulk of __dquot_initialize runs under the dqptr_sem which protects the inode->i_dquot pointers. It doesn't protect the dereferenced contents, though. Those are protected by the dq_data_lock, which is missing around the dquot_resv_space call. Signed-off-by: NJeff Mahoney <jeffm@suse.com> Signed-off-by: NJan Kara <jack@suse.cz>
