That makes no sense. If it used to work before that patch, then this is a regression and the patch needs to be reverted. Yes, the old code apparently used to set "o2hb_debug_dir" to an error pointer when debugfs was compiled out, but since debugfs was compiled out, that error pointer was probably never actually *used*. So things presumably worked. Now, it hangs, according to Huang Ying. If so, that's clearly a regression. That means that commit e2ac55b6a8e3 ("ocfs2: incorrect check for debugfs returns") needs to be reverted or fixed. Andrew?
