Rosen Penev e4df433b8a btrfs-progs: treewide: Replace strerror(errno) with %m. ... As btrfs is specific to Linux, %m can be used instead of strerror(errno) in format strings. This has some size reduction benefits for embedded systems. glibc, musl, and uclibc-ng all support %m as a modifier to printf. A quick glance at the BIONIC libc source indicates that it has support for %m as well. BSDs and Windows do not but I do believe them to be beyond the scope of btrfs-progs.
