Changes to this file should not be MFCed. +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. + r354517: iwm(4) now supports most Intel 9260, 9460 and 9560 Wi-Fi devices.
