prevent inodes from vanishing, but ihold() does not guarantee inode persistence. Replace the inode pointer with a per boot, machine wide, unique inode identifier. The second commit fixes the breakage of the hash mechanism whihc causes a 100% performance regression. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAl5uQJsTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoYp4EAC5fr/AyRaIn/AEIZUmoyK6ELUaknfH Z788avxDB/t5GkzC9A2dMpybYi78tzLSAEfB8jYgwbrqExapVtiqvjGZ1RIi3HoN f/DWLnOb2s+yYQ3BQlHu4RdKONEzCqBwKFpElGRv3JzCY8Qeh5cQBzdqzvOEFmYw P7DJVtJRZ2dud7AzJ+xk6KuNIKCT2F7Djmtop6nq1EVw0J/2oYOVgQu76APBj7cj 32srLmpP4xcQiJmWLC5ksXKiZrMPnyNfwXhHFufNvJ2Re6+Wf8mmglqG/5DmA+Ns Sq3L7D7yXwtWQZ8Po1qnWhPDZVXQbWzHyTn4YAMJAK7yoO7mut8jgECt+A8vf4L+ hsc41c6THfdCQQ9gmxLL+c08nZGlmvIC4/1RsihNZ3kd2o4k6Ah9xFp8lBFcpjWd 7tuhakNqJvUOvB34t2AYqzMFbZ/FJG+QNGyIW0bTUn4YIgRPxI/zsdMxqGVBZ4oN 0iuy1kPLGbGAnLU9thkiVMmAyaPesuiB6f+mmzobEUgGI35GrCJi6a4YaTG1sqFn Gl8oPzcU2n+DWbVBfJrVFHJye7oi78kCw6wpNLBCJQp8NP8doAH0Sgspglg52E/p G4GGLz0vGauHBC5wQ3WYiGLImWbzC1dwKdcNE7dhuTgXbhz8ChVlOSU9Fu4+pGpq 6URL6DVTLwDZPg== =e2iB -----END PGP SIGNATURE----- Merge tag 'locking-urgent-2020-03-15' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull futex fix from Thomas Gleixner: "Fix for yet another subtle futex issue.
