Pull request overview
This PR enables virtiofs tests that were previously disabled due to bugs in the virtiofs implementation (specifically in lxutil), and conditionally skips one test (DrvFsTestDeleteCurrentWorkingDirectory) that has race condition issues on virtiofs. The changes are supported by an update to the Microsoft.WSL.DeviceHost package which contains the necessary bug fixes.
- Enables
VerifyDrvFsLxSymlinktest cases for virtiofs that were previously skipped - Skips the
DrvFsTestDeleteCurrentWorkingDirectorytest for virtiofs due to race conditions - Updates package dependency to include virtiofs bug fixes
