+r355677:
+ Adds support for NFSv4.2 (RFC-7862) and Extended Attributes
+ (RFC-8276) to the NFS client and server.
+ NFSv4.2 is comprised of several optional features that can be supported
+ in addition to NFSv4.1. This patch adds the following optional features:
+ - posix_fadvise(POSIX_FADV_WILLNEED/POSIX_FADV_DONTNEED)
+ - posix_fallocate()
+ - intra server file range copying via the copy_file_range(2) syscall
+ --> Avoiding data tranfer over the wire to/from the NFS client.
+ - lseek(SEEK_DATA/SEEK_HOLE)
+ - Extended attribute syscalls for "user" namespace attributes as defined
+ by RFC-8276.
+
+ For the client, NFSv4.2 is only used if the mount command line option
+ minorversion=2 is specified.
+ For the server, two new sysctls called vfs.nfsd.server_min_minorversion4
+ and vfs.nfsd.server_max_minorversion4 have been added that allow
+ sysadmins to limit the minor versions of NFSv4 supported by the nfsd
+ server.
+ Setting vfs.nfsd.server_max_minorversion4 to 0 or 1 will disable NFSv4.2
+ on the server.
+
