Subject: [PATCH] Add mctx attach/detach when creating/destroying a memory pool
|
||
|
|
|
||
|
|
This should make sure that the memory context is not destroyed
|
||
|
|
before the memory pool, which is using the context.
|
||
|
|
|
||
|
|
(cherry picked from commit e97c3eea954e055634b72c21325d2611e960ee94)
