It seems = like a simple enough patch for other trees. >=20 >=20 > OK, so it=E2=80=99s a necessary patch for other trees? I=E2=80=99ll = apply it on our local copy, but for data corruption issues like this it = seems like an MFC or a patch to a release branch would be good. Replying to myself after a bit more investigation =E2=80=94 this patch = fixes a problem introduced in r287699, which is only in head. As far as = I can see no action is required for stable/10.
