Subject: [PATCH 75/75] libhns: Fix unnecessary dca memory detach
|
||
|
|
|
||
|
|
driver inclusion
|
||
|
|
category: bugfix
|
||
|
|
bugzilla: https://gitee.com/src-openeuler/rdma-core/issues/I8J2Y5?from=project-issue

--------------------------------------------------------------------------

|
|
If sq is not enabled, it should not detach dca mem. Moreover, under the
|
||
|
|
current code logic, if detach dca mem, its sq index will be a random
|
||
|
|
value because it is not initialized.
