| 4 | Subject: [PATCH] compat: work around broken _SC_NPROCESSORS_CONF on MUSL libc | ||
| 5 | |||
| 6 | On MUSL libc the _SC_NPROCESSORS_CONF sysconf will report the number of | ||
| 7 | CPUs allocated to the task based on the affinity mask instead of the | ||
| 8 | total number of CPUs configured on the system. | ||
| 9 | |||
