From 5e413cad10d2358a21dd08216953faee70e62a0b Mon Sep 17 00:00:00 2001 From: Dean Deng Date: Sat, 14 Mar 2020 07:13:15 -0700 Subject: Plumb VFS2 imported fds into virtual filesystem. - When setting up the virtual filesystem, mount a host.filesystem to contain all files that need to be imported. - Make read/preadv syscalls to the host in cases where preadv2 may not be supported yet (likewise for writing). - Make save/restore functions in kernel/kernel.go return early if vfs2 is enabled.
