Linus Torvalds 310c7585e8 Olga added support for the NFSv4.2 asynchronous copy protocol. We ... already supported COPY, by copying a limited amount of data and then returning a short result, letting the client resend. The asynchronous protocol should offer better performance at the expense of some complexity. The other highlight is Trond's work to convert the duplicate reply cache to a red-black tree, and to move it and some other server caches to RCU. (Previously these have meant taking global spinlocks on every RPC.) Otherwise, some RDMA work and miscellaneous bugfixes. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJb2KWzAAoJECebzXlCjuG+gcQP/3DldB86CFxgSFx0t+h+s+TV CdYJDPyLyRkEMiD+4dCPPuhueve+j5BPHVsDbn98FTWrEn131NMIs6uhU/VGTtAU 6a8f/ExtZ5U7s39MJCzlk2ozVElBc3QPp7p3p9NKn0Wi0PXbVgjuIqR5o2vwa8Si KOVdLm6ylfav/HTH8DO6zFPJRsTgTwcJOivXXshjpglMKAcw8AuqSsGgBrDeGpgU u91Vi0EM1vt96+CA6a01mTgC/sFX7EqGvxUUHOrKWf5cIjnpT3FDvouYPxi+GH8Z SIDlaMQyXF5m4m6MhELNTP4v97XAHyPJtvLkEe5lggTyABPiA2heo9e8onysWkzV 1v8OZHCVFa1UL34mDlnFxbFCYVr7FFKMGjTBR/ntinobPfAbWRCO1Hdd+bBGPDD4 byf7ctDVp7KQ2bSatIdlYavikuGDHWFDZHzPHlqkD3gpIZSNvhe26sV3NZqIFlXO cMUega2Y5mXmULauHhxAcNGtDK7dF5hHoMWKJy0DNxiyDiDLylwDOIfwt1De3Q7V ycd/wUytUS2LkAhyS2mvoDK6eXTBAeQwzmXAqveh6rewwO83HC/t9mtKBBDomvKG xRpRPmmbj9ijbwkilEBmijjR47wrihmEVIFahznEerZ+//QOfVVOB0MNtzIyU9/k CnP1ZNvOs3LR1pxxwFa8 =TTo0 -----END PGP SIGNATURE----- Merge tag 'nfsd-4.20' of git://linux-nfs.org/~bfields/linux Pull nfsd updates from Bruce Fields: "Olga added support for the NFSv4.2 asynchronous copy protocol.
