Andrew Geissler | d1e8949 | 2021-02-12 15:35:20 -0600 | [diff] [blame^] | 4 | Subject: [PATCH 14/26] Do not disable buffering when writing to oom_score_adj |
Brad Bishop | 1932369 | 2019-04-05 15:28:33 -0400 | [diff] [blame] | 5 | |
| 6 | On musl, disabling buffering when writing to oom_score_adj will |
| 7 | cause the following error. |
| 8 | |
| 9 | Failed to adjust OOM setting: Invalid argument |
| 10 | |
| 11 | This error appears for systemd-udevd.service and dbus.service. |
| 12 | This is because kernel receives '-' instead of the whole '-900' |
| 13 | if buffering is disabled. |
| 14 | |
| 15 | This is libc implementation specific, as glibc does not have this issue. |
| 16 | |
| 17 | Upstream-Status: Inappropriate [musl specific] |
