+Subject: [PATCH] Makefile.in: install static library and headers in
+ install-static
+
+Currently, the install-static target only installs the statically
+compiled tools. However, some programs outside of btrfs-progs (for
+example docker) link with the btrfs libraries. If such programs want
+to link statically against the btrfs-progs library, then this library
+should be installed by "install-static". Indeed, "make install" cannot
+be used if the support for shared library is not enabled.

+Subject: [PATCH] kerncompat.h: define BTRFS_DISABLE_BACKTRACE when building
+ with uClibc
+
+uClibc does not provide backtrace() nor <execinfo.h>. When building
+btrfs-progs, passing --disable-backtrace is enough to make it build with
+uClibc. But once btrfs-progs is installed and another program/library
+includes kerncompat.h, it fails to build with uClibc, because
+BTRFS_DISABLE_BACKTRACE is not defined.
+
+The most correct fix for this would be to have kerncompat.h generated
+from kerncompat.h.in during the btrfs-progs build process, and tuned
+depending on autoconf/automake variables. But as a quick fix that
+follows the current strategy, we simply tweak the existing __GLIBC__
+conditional. Indeed, uClibc pretends to be glibc and defines __GLIBC__,
+but it does not replace it completely, hence the need to define
+BTRFS_DISABLE_BACKTRACE when __GLIBC__ is not defined *or* when
+__UCLIBC__ is defined.
