Subject: [PATCH 3/4] libhns: Fix memory leakage when DCA is enabled
|
||
|
|
|
||
|
|
After DCA is enabled and a QP is created, the memory block
|
||
|
|
applied for DCA is not free when the QP is destroyed. Here
|
||
|
|
fix it.
|
||
|
|
|
||
|
|
Fixes: 3aa4683ef700 ("libhns: Add support for attaching QP's WQE buffer")
