NFS client fixes for Linux 5.2
Stable bugfixes: - SUNRPC: Fix regression in umount of a secure mount - SUNRPC: Fix a use after free when a server rejects the RPCSEC_GSS credential - NFSv4.1: Again fix a race where CB_NOTIFY_LOCK fails to wake a waiter - NFSv4.1: Fix bug only first CB_NOTIFY_LOCK is handled Other bugfixes: - xprtrdma: Use struct_size() in kzalloc() -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEnZ5MQTpR7cLU7KEp18tUv7ClQOsFAlz4KzoACgkQ18tUv7Cl QOt7OhAAvG+DVZ6V5+q4zvabKgoievlL56Ys4SaAp3+OlxC6VaiyQUDs/6U9C/xH dmVbGYWdFXjqJE1JPXxmu0jOdRiZcnhIq+hiHNOK0qZOBCnE5zzZ1r1tdNY0GHQ2 JOkREqsXsaeUWuO0pCY7JOmzd5aU1XLhg1/8+9Z7gNwamMfwLkEqi7FGtXi+xsGz gQVxMJlHsV2F21IKdKS0TJrcqr2okya/MnOQRbbMC2RT/MYNxDrhAPBJ1Shcx3HB NlccAn4jhIL0bCPRvFPib6KrO01U0Ye/KECN8j2qHRT4QS2s0dsnnQ6f2tEs9mJ8 cRTVh1uniF6ZuDxSr6KIIN3mKA9DX2SK83H16ahAaRBLM8dwF+4MIr6gDdtJvsVw nY0YDpnAaKFypuCPBV/jFu7fk97hul4ntymJGVeFdlqu/HtWs1Z1iM93DDVJbKr8 a3AND6woOQ2asvySPo+X66PKt79gofga4C+ZDuMfJax8+K9imqIyforgLrAmd/yL sGAlLzenf6fmOB5C1bPTtrFFbs6XiHXMidDGwmm1kOZIDuN+O2TTwc24gyXx0IyJ OhmjDn2CKmzS2WVPhetRgurzkdTigJu4PebC421qWSFhxlf/NfghW+rpM9su/hwv /r9+bpdjZ8YD5FUJvxsX4NZLr+SWbNTzX/ARNdRFsGr0NLpG/50= =rrp/ -----END PGP SIGNATURE----- Merge tag 'nfs-for-5.2-2' of git://git.linux-nfs.org/projects/anna/linux-nfs Pull NFS client fixes from Anna Schumaker: "These are mostly stable bugfixes found during testing, many during the recent NFS bake-a-thon.
