* Fix a lock inversion between scheduler and RCU introduced in v6.2-rc4. The scenario could trigger on any user of RCU_NOCB (mostly Android and also nohz_full). * Fix PF_IDLE semantic changes introduced in v6.6-rc3 breaking some RCU-Tasks and RCU-Tasks-Trace expectations as to what exactly is an idle task. This resulted in potential spurious stalls and warnings. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEd76+gtGM8MbftQlOhSRUR1COjHcFAmVFB/QACgkQhSRUR1CO jHctUg/+LjAHNvT8YR99qxP3v8Ylqf191ADhDla1Zx1LYkhcrApdRKQU5G1dzfiF arJ/KSSgCLCYMecwdh6iOL5s3S3DtQGsh7Y7f/dJ6vwJbNe2NbPaMYK2WQ171zT+ ht7oAugFrOpWn5H6i1eC170N+rG7nHYuCXrzsta0fx1fOp9G0OeemvweD7HjpaB7 66tp0KnuJWLfPLoZucscxKRtC7ZG0zDztFUXcfcv+TQE6w5fXuhtLX7E7fE1jPMr Pa3x9Su5fjFCRJCCCFNHzKqbf8VKG/teGOONFBwt8AwwU1/7TuIuwSOjrISOaG91 eEeIwWyiAw+aP+7CMMGca0oYPOR+b3Xq7vmN85KIEFUHpNls6MvR5/itR1d3/FsA 9EkiNLIwbRV9ICi+JeGeJsSmm6TRJL4XToiw9fJKfC05IHjotMSAtUOqHS/VmdjL o1kDdiWBSHUy7VVelu5wRHb0WINc9Zrq/tc3MT2W0EpTDRSL2r04MsP8UDYre1oY KDdTLSPsy2D+5YWY484Z+bCOHl0bXSgZe4PycGVrP9HEus6MGHyxU6uDCXwWbqQz R0QdZ60AdquwWTdK1K0PsU5VKQw3oZKKwj8hyKOr31NpSZ1FvLJa8Ct8D2UZPbMS WNscgGE4ZNjCYFq8wtnL5LkUym8is1Y6/nLifBV1scx5GtyHYiU= =a5L7 -----END PGP SIGNATURE----- Merge tag 'rcu-fixes-v6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks Pull RCU fixes from Frederic Weisbecker: - Fix a lock inversion between scheduler and RCU introduced in v6.2-rc4.
