+Subject: [PATCH] btrfs-progs: include linux/const.h to fix build with 5.12+
+ headers
+
+btrfs-tools compile fails with mips, musl and 5.12+ headers.
+
+The definition of __ALIGN_KERNEL has moved in 5.12+ kernels, so we
+add an explicit include of const.h to pickup the macro:
+
+ | make: *** [Makefile:595: mkfs.btrfs] Error 1
+ | make: *** Waiting for unfinished jobs....
+ | libbtrfs.a(volumes.o): in function `dev_extent_search_start':
+ | /usr/src/debug/btrfs-tools/5.12.1-r0/git/kernel-shared/volumes.c:464: undefined reference to `__ALIGN_KERNEL'
+ | collect2: error: ld returned 1 exit status
+
+This is safe for older kernel's as well, since the header still
+exists, and is valid to include.

+Subject: [PATCH] btrfs-progs: include sys/sysinfo.h conditionally on musl
+
+Make inclusion of sys/sysinfo.h conditional to avoid the following build
+failure on musl:
+
+In file included from .../i586-buildroot-linux-musl/sysroot/usr/include/linux/kernel.h:4,
+ from ./kerncompat.h:31,
+ from common/utils.c:42:
+.../i586-buildroot-linux-musl/sysroot/usr/include/linux/sysinfo.h:7:8: error: redefinition of 'struct sysinfo'

+
+Fixes:
+ - http://autobuild.buildroot.org/results/16f44fb9dea72a7079e8e5517e760dd79d2724cc
+
+The 'struct sysinfo' is defined in linux/sysinfo.h and sys/sysinfo.h,
+while both must not be included at the same time. Stop including
+linux/kernel.h that sometimes unconditionally includes sys/sysinfo.h and
+causes the double definition for some reason. As we now include
+linux/const.h directly, there's no other effective change.
