From: Xiubo Li <xiubli@xxxxxxxxxx> This patch series is based on Jeff Layton's previous great work and effort on this and all the patches have been in the testing branch and well tested: The qa teuthology tests results: https://pulpito.ceph.com/xiubli-2023-06-09_03:59:14-fs:fscrypt-wip-lxb-fscrypt-20230607-0901-distro-default-smithi/ Since v15 we have added the ceph qa teuthology test cases for this [1][2], which will test both the file name and contents encryption features and at the same time they will also test the IO benchmarks. To support the fscrypt we also have some other work in ceph [3][4][5][6][7][8][9]: [1] https://github.com/ceph/ceph/pull/48628 [2] https://github.com/ceph/ceph/pull/49934 [3] https://github.com/ceph/ceph/pull/43588 [4] https://github.com/ceph/ceph/pull/37297 [5] https://github.com/ceph/ceph/pull/45192 [6] https://github.com/ceph/ceph/pull/45312 [7] https://github.com/ceph/ceph/pull/40828 [8] https://github.com/ceph/ceph/pull/45224 [9] https://github.com/ceph/ceph/pull/45073 The [9] is still undering testing and will soon be merged after that. All the others had been merged. The main changes since v19: - s/ceph_open/ceph_lookup/ for [PATCH v20 70/71]. - Updated the patches to fix use-after-free bug for fscrypt_destroy_keyring, the link https://patchwork.kernel.org/project/ceph-devel/list/?series=755131.
