I understand your concern about this, but does is make sense to not use -9 when then following files use gzip or other compression tools with -9 : arch/blackfin/Makefile:14:GZFLAGS := -9 arch/powerpc/boot/wrapper:297: gzip -n -f -9 "$vmz.$$" arch/powerpc/boot/wrapper:422: gzip -n -f -9 "$ofile" arch/powerpc/boot/wrapper:469: gzip -n --force -9 --stdout "$ofile.bin" > "$odir/otheros.bld" arch/arm/Makefile:23:GZFLAGS :=-9 arch/arm64/Makefile:16:GZFLAGS :=-9 arch/m68k/Makefile:138: gzip -9c vmlinux.tmp >vmlinux.gz arch/m68k/Makefile:141: gzip -9c vmlinux >vmlinux.gz arch/mips/lasat/image/Makefile:46: gzip -cf -9 $< > $@ arch/parisc/Makefile:121: @gzip -cf -9 $< > $@ scripts/package/mkspec:115:echo 'bzip2 -9 vmlinux' scripts/package/builddeb:20: gzip -9 "$pdir/usr/share/doc/$pname/changelog.Debian" scripts/package/Makefile:127: -f -9 $(perf-tar).tar) scripts/gen_initramfs_list.sh:229:compr="gzip -n -9 -f" scripts/gen_initramfs_list.sh:245: && compr="gzip -n -9 -f" scripts/gen_initramfs_list.sh:248: && compr="bzip2 -9 -f" scripts/gen_initramfs_list.sh:251: && compr="lzma -9 -f" scripts/gen_initramfs_list.sh:257: && compr="lzop -9 -f" scripts/gen_initramfs_list.sh:260: && compr="lz4 -l -9 -f" scripts/Makefile.lib:241:cmd_gzip = (cat $(filter-out FORCE,$^) | gzip -n -f -9 > $@) || \ scripts/Makefile.lib:311: bzip2 -9 && $(call size_append, $(filter-out FORCE,$^))) > $@ || \ scripts/Makefile.lib:319: lzma -9 && $(call size_append, $(filter-out FORCE,$^))) > $@ || \ scripts/Makefile.lib:324: lzop -9 && $(call size_append, $(filter-out FORCE,$^))) > $@ || \ -- Beber -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
