| Subject: [PATCH] do not disable buffer in writing files |
| |
| Do not disable buffer in writing files, otherwise we get |
| failure at boot for musl like below. |
| |
| [!!!!!!] Failed to allocate manager object. |
| |
| And there will be other failures, critical or not critical. |
| This is specific to musl. |
| |
| Upstream-Status: Inappropriate [musl] |
