Subject: [RFC v1 04/16] perf kwork: Add `kwork` and `src_type` to work_init() for struct kwork_class
Date:   Sat, 12 Aug 2023 08:49:05 +0000
Message-ID: <20230812084917.169338-5-yangjihong1@huawei.com>
In-Reply-To: <20230812084917.169338-1-yangjihong1@huawei.com>

Precedence: bulk

To support different types of reports, two parameters
`struct perf_kwork * kwork` and `enum kwork_trace_type src_type` are added
to work_init() of struct kwork_class for initialization in different
scenarios.

No functional change.
