| Subject: [PATCH] Do not disable buffering when writing to oom_score_adj |
| |
| On musl, disabling buffering when writing to oom_score_adj will |
| cause the following error. |
| |
| Failed to adjust OOM setting: Invalid argument |
| |
| This error appears for systemd-udevd.service and dbus.service. |
| This is because kernel receives '-' instead of the whole '-900' |
| if buffering is disabled. |
| |
| This is libc implementation specific, as glibc does not have this issue. |
| |
| Upstream-Status: Inappropriate [musl specific] |
