+Subject: [PATCH] unifdef: drop unused errno.h include
+
+This is the only header on my system that ends up requiring kernel
+headers, so if the kernel headers aren't available, we end up being
+unable to install kernel headers :).
+
+Since this file doesn't actually use anything from errno.h, drop
+the include so it at least makes us a bit more robust on glibc.

+Subject: [PATCH] netlink: drop (int) cast on length arg in NLMSG_OK
+
+The NLMSG_OK macro compares three things:
+ - the len arg from the user
+ - a size_t: sizeof(struct nlmsghdr)
+ - an int: sizeof(struct nlmsghdr) casted
+ - an u32: the nlmsghdr->nlmsg_len member
+
+When building with -Wsign-compare, this macro triggers a signed compare
+warning.  This is because it compares len to an int, and then compares
+it to a u32.  If len is signed, we get a warning due to the last test.
+If len is unsigned, we get a warning due to the first test.  Like in
+strace:
+socketutils.c:145:8: warning: comparison between signed and unsigned
+                              integer expressions [-Wsign-compare]
+
+Lets drop the int cast on the first sizeof.  This way, once the user
+casts len to an unsigned value, everything shakes out correctly.

+
+including sysinfo.h from kernel.h makes no sense whatsoever,
+but removing it breaks glibc's userspace header,
+which includes kernel.h instead of sysinfo.h from their sys/sysinfo.h.
+this seems to be a historical mistake.
+on musl, including any header that uses kernel.h directly or indirectly
+plus sys/sysinfo.h will produce a compile error due to redefinition of
+struct sysinfo.h.
+so for now, only include it on glibc in order not to break their 
+headers.
