Filipe's looking at this Sage, you said it happend on v3.13-rc2 but the
kernel line says 3.14.0-rc5, have you had it happen in both places? Thanks,
Whoops, that's my mistake.. it's 3.14-rc5. The exact commit is it
git://github.com/ceph/ceph-client.git, if it matters; it's -rc5 + some
ceph patches.
Cool, not worried about what you guys are doing, just wondering if it
may be related to me screwing around in delayed ref land recently or if
you had seen it earlier too. Thanks,
Josef
