   4 Subject: devlink: fix libc and kernel headers collision
   5
   6 Since commit 2f1242efe9d ("devlink: Add devlink health show command") we
   7 use the sys/sysinfo.h header for the sysinfo(2) system call. But since
   8 iproute2 carries a local version of the kernel struct sysinfo, this
   9 causes a collision with libc that do not rely on kernel defined sysinfo
  10 like musl libc:

  24 Move the sys/sysinfo.h userspace header before kernel headers, and
  25 suppress the indirect include of linux/sysinfo.h.
