In general the sort of testing that it's good for is "this needs more exposure" sorts of things - things that look good locally but where there's a wide variety of users or affected systems that might be affected and where it's hard to judge the impact. > > Do you see any technical problems except comment style problem? > The above errors are already a technical problem -- they break the > Clippy and docs build! Oh, bah - something turned off RUST in allmodconfig again so we lost coverage in -next, sorry about that. I'll need to work something out to make sure I notice that happening and can do something about it. It's kind of worrying that this keeps happening TBH, otherwise rust conflicts are likely to result in broken builds. The dependencies feel really fraigle here. > No, please drop it now -- the patch shouldn't have been applied to > linux-next yet, since the maintainers didn't ack it (they just > realized it exists...), it is not reviewed (apart from Sashiko), it is > not tested enough (given the errors above) and not destined for the > next merge window (for all the reasons before). Had the rust builds been enabled for allmodconfig as I had expected the tree would have been kept out of -next as a result of this. --StAMqoMBl4zgWmc9 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmoiu08ACgkQJNaLcl1U h9AjUAf+KvxHG2EpNg/5WRLFMD+usuVYU6396FrVd3qAnwYZHZ4NL8YKbVSH0xE0 BiOzCycX8KKLq55wHPy+v9DB1PUGCHhMHCXbcgMXWUtXNCKXlz3K8lH2btLADSkE sS4Fh28CoDPhVREPITYhRb3QwRHtztwqcayblFxM3Epm3cEtJzET5qgFKbGtKbFq arb2USdnn0IP5z6FhTxm4Joco+c6QSfHDCCbFXyFfKhIK4lpK0KhJBp675uFTkgH RIkRTr6cKEc+yg7wi2koWA/g39rMQxEUHHqVRxu5lsHcXad4ctmFrvnuHP6HvYpP V7DbGAnI18515PvWAvMPafYsIY11nQ== =qEAs -----END PGP SIGNATURE----- --StAMqoMBl4zgWmc9--
