The build system can currently only compress files. This patch adds the functionality to decompress files. Decompression is needed for building firmware files into the kernel if those files are compressed on the filesystem. Compressed firmware files are in use by Gentoo, Fedora, Arch, and others. Signed-off-by: Kevin Martin <kevinmbecause@gmail.com> --- Changes in v2: - Skipped running 'cat' and now just pass the file names directly. - Added '--quiet' since 'zstd' started printing the status of each file now that it knows the file names. scripts/Makefile.lib | 6 ++++++ 1 file changed, 6 insertions(+)
