Dominique seems to at least not see it any more with > that patch. I've had Al's patch under load since this morning, and it's going fine. But I've not actually managed to reproduce the issue for several days now, however bogus a "fix" I've been testing. So certainly don't wait to hear from me: but of course I'll keep on with the loads, and shout if it does go wrong again. (I don't actually understand why the clearing of DCACHE_ENTRY_TYPE in dentry_iput() is not of continuing concern; but don't worry, there's plenty I don't understand - so long as you're both satisfied that it's not a concern, no need to persuade me.) Do we have any idea why a bug introduced in v3.13 should only now stand out, both for Dominique and for me? Has the RCU lookup somehow become much more effective recently? (I don't think symlinks were a big deal for either of us, though the kernel build does use some).
