Subject: [PATCH] vddk: Drop obsolete documentation related to thread model
|
|
|
|
Since commit 1eecf15fc3 ("vddk: Implement parallel thread model") we
|
|
have implemented a parallel thread model in this plugin, and thread
|
|
handling is believed to be safe and in conformity with the VDDK
|
|
documentation. Remove obsolete documentation contradicting this.
|
|

Fixes: commit 1eecf15fc3d8ea253ccec4f5883fdbb9aa6f8c2b
