Yes, these do look suspicious.  I'll test reverting them tonight.

OK, I'd suggest reverting the VFS change (18e9e5104fcd9a9) first.

Turns out it was 6b0310fbf087ad6 that did it. CCing Eric Sandeen since he wrote it. Eric, this patch seems to cause a deadlock when taking an lvm snapshot of the root lv. Any idea why?
