  "message": "fs: provide simple rcu-walk generic_check_acl implementation\n\nThis simple implementation just checks for no ACLs on the inode, and\nif so, then the rcu-walk may proceed, otherwise fail it.\n\nThis could easily be extended to put acls under RCU and check them\nunder seqlock, if need be. But this implementation is enough to show\nthe rcu-walk aware permissions code for path lookups is working, and\nwill handle cases where there are no ACLs or ACLs in just the final\nelement.\n\nThis patch implicity converts tmpfs to rcu-aware permission check.\nSubsequent patches onvert ext*, xfs, and, btrfs. Each of these uses\nacl/permission code in a different way, so convert them all to provide\ntemplates and proof of concept.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n",
