Fix the locking around nouveau's use of the hmm_range_* APIs. It works correctly in the success case, but many of the the edge cases have missing unlocks or double unlocks. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEfB7FMLh+8QxL+6i3OG33FX4gmxoFAl07BG0ACgkQOG33FX4g mxr/RA//b1t3rTjyYlzEGpCFouDAJrV8mRrmPZtywzSxhiyKgylWiQ9D5HyAZ8ZG evEF1xFe0PcTKiieqnZCJBPh864t+yt9Mm45MpWamBNoHx7WPSdeOMbSDUNvQR+H 8aWTGBZvdKlqpwD63yvk7C6jkZ6vXDNYROnM395gzlfmaVGBeLygXqcKUkiW1x+D 1CK+KsBldacxH/gE2X966mXxG46/5VL8KDVoo4VVnpLMDRdRs6zbIBRj7l9+hWbh 2HABQyvDJW4tYmUW5iHAoLV2fAIE/nJMprEabXvd6rFAPwbryBroguXffGqkIaa0 Ce1LIhiakCUniK2XgP2W/+KwJQBNp3hQjJr+ip7hgQCtzcD8zRYSxDt5gUtbjpGd 4JfXrRVrfa08/hBe4adPfE5W5mW3oyEyRHldToT0SrywIY8sTLjN7RdCMwOqrxoR QkgqDISLqJab1OQEPHr7QgsgO2c2k19yPpckSZJ+IIldpNtLa9V+eif85NZ/esOd 2GTWph3UQiACp9fLgEIAvJUnZ0blZpYq9TYshWWYkO34M+KgBdqOn1cQhZH+4rWb 0Ed/jGdIaPZZ7XaLDgz5e7jl+t+kmSBdqSQtunF4bbu7AwR/zt3es0jq2vFoD451 syF2vSVKyoBZMESX8X0O2cv+HHpN5oqH1XLI1ABOO09X9lxAPl4= =ZdrW -----END PGP SIGNATURE----- Merge tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma Pull HMM fixes from Jason Gunthorpe: "Fix the locking around nouveau's use of the hmm_range_* APIs. It works correctly in the success case, but many of the the edge cases have missing unlocks or double unlocks. The diffstat is a bit big as Christoph did a comprehensive job to move the obsolete API from the core header and into the driver before fixing its flow, but the risk of regression from this code motion is low" * tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: nouveau: unlock mmap_sem on all errors from nouveau_range_fault nouveau: remove the block parameter to nouveau_range_fault mm/hmm: move hmm_vma_range_done and hmm_vma_fault to nouveau mm/hmm: always return EBUSY for invalid ranges in hmm_range_{fault,snapshot} |
