Subject: [PATCH] support ranges when parsing CPUAffinity |
|
|
|
The functionality was implemented in https://github.com/systemd/systemd/pull/1699/. |
|
However, it is not backportable without considerable code changes. |
|
|
|
Implement parse_range() and parse_cpu_set_and_warn() from the upstream master |
|
branch and use them in appropriate places. Also introduce relevant tests. |
|
|
|
Resolves: #1493976 |
