vhost_user_fs: Add new crate This new crate will be dedicated to vhost_user_fs specific code that can be used as a library from the vhost-user-fs daemon. Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com> 2019-10-31 17:16:28 +00:00			`// Copyright © 2019 Intel Corporation`

vhost_user_fs: Add FUSE definitions To be able to deal with FUSE requests, this commit introduces FUSE definitions, copied over from the crosvm commit 961461350c0b6824e5f20655031bf6c6bf6b7c30. Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com> 2019-10-31 17:26:24 +00:00
vhost_user_fs: Implement FileSystem trait for Passthrough Add a "passthrough" file system implementation that just forwards its requests to the appropriate system call. This code has been ported over from crosvm commit 961461350c0b6824e5f20655031bf6c6bf6b7c30. Signed-off-by: Sebastien Boeuf <sebastien.boeuf@intel.com> 2019-10-31 20:09:20 +00:00			`#[macro_use]`

vhost_user_fs: Add file traits to handle writing volatile memory The vm_memory implementation for VolatileSlice is able to read and write to a source or destination which implements a Read or Write trait. Unfortunately, this is not enough for this specific use case as we need to be able to write to a file at a specific offset, which is not provided by the Read or Write trait. This code has been ported over from crosvm commit 961461350c0b6824e5f20655031bf6c6bf6b7c30.

vhost_user_fs: Add FileSystem trait Add the `Filesystem` trait, which is the main interface between the transport and the actual file system implementation.

vhost_user_fs: Add multikey module The multikey module provides a BTreeMap implementation that can use one of 2 different kinds of keys to look up a value. This is needed by the virtio-fs server since it needs to be able to look up keys either by u64 or by a (ino_t, dev_t) pair.
