Subject: [PATCH] Avoid redefinition of struct ethhdr
|
||||
|
||||
This is a workaround to the if_ether.h conflict between musl and the kernel.
|
||||
Both define struct ethhdr.

Subject: [PATCH] Make scheduler functions Linux-compatible
|
||||
|
||||
Let sched_getscheduler(), sched_setscheduler(), sched_getparam(),
|
||||
sched_setparam() invoke the Linux syscalls of the same name instead
|
||||
of returning -ENOSYS.
