Subject: [PATCH 092/189] net/hns3: fix concurrent interrupt handling
|
|
|
|
Currently, if RAS interrupt and FLR occurred at the same time, FLR will
|
|
be detected and corresponding schedule state will be set during RAS
|
|
interrupt processing. However, the schedule state value will be
|
|
overridden in subsequent RAS processing, resulting in FLR processing
|
|
failure. This patch solves this problem.
|
|
|
|
Fixes: 2790c6464725 ("net/hns3: support device reset")
