Revision 33d283bef23132c48195eafc21449f8ba88fce6b authored by Li Zefan on 19 November 2008, 23:36:48 UTC, committed by Linus Torvalds on 20 November 2008, 02:50:00 UTC
Try this, and you'll get oops immediately: # cd Documentation/accounting/ # gcc -o getdelays getdelays.c # mount -t cgroup -o debug xxx /mnt # ./getdelays -C /mnt/tasks Because a normal file's dentry->d_fsdata is a pointer to struct cftype, not struct cgroup. After the patch, it returns EINVAL if we try to get cgroupstats from a normal file.
