* btrfs-progs: treewide: Replace strerror(errno) with %m.Rosen Penev2018-01-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* btrfs-progs: fssum: fix warning, include correct header for major()David Sterba2017-05-02
| | | | | | | | | | | | tests/fssum.c:599:13: warning: In the GNU C Library, "major" is defined by <sys/sysmacros.h>. For historical compatibility, it is currently defined by <sys/types.h> as well, but we plan to remove this soon. To use "major", include <sys/sysmacros.h> directly. If you did not intend to use a system-defined macro "major", you should undefine it after including <sys/types.h>. sum_add_u64(&cs, major(st.st_rdev)); Signed-off-by: David Sterba <dsterba@suse.com>
