This reverts commit 4e17b1126e.
|
|
|
586cba |
|
|
|
586cba |
Over time AioContext usage and coverage has increased, and now block
|
|
|
586cba |
backend is capable of handling AioContext change upon eject and insert.
|
|
|
586cba |
Therefore the above downstream-only commit is not necessary anymore,
|
|
|
586cba |
and can be safely reverted.
