[PATCH v4 04/11] hw/9pfs/9p-synth: added directory for readdir test |
Date: |
Tue, 21 Jan 2020 01:01:56 +0100 |
This will provide the following virtual files by the 9pfs
synth driver:
- /ReadDirDir/ReadDirFile99
- /ReadDirDir/ReadDirFile98
...
- /ReadDirDir/ReadDirFile1
- /ReadDirDir/ReadDirFile0
This virtual directory and its virtual 100 files will be
used by the upcoming 9pfs readdir tests.
