tools/depmod: use nsec granularity when checking timestamps

Current code uses the POSIX.1-2001 stat::st_mtime which has one second
granularity. Considering the depmod execution time may be smaller, we
should be using the POSIX.1-2008 stat::st_mtim which has nano-second
granularity instead.

kmod - Linux kernel module handling

OVERVIEW

kmod is a set of tools to handle common tasks with Linux kernel modules like insert, remove, list, check properties, resolve dependencies and aliases.

These tools are designed on top of libkmod, a library that is shipped with kmod. See libkmod/README for more details on this library and how to use it. The aim is to be compatible with tools, configurations and indexes from module-init-tools project.

Compilation and installation

In order to compile the source code you need:

  • C11 compiler, supporting a range of GNU extensions - GCC 8+, Clang 6+
  • POSIX.1-2008 C runtime library - Bionic, GNU C library, musl

Optional dependencies, required with the default build configuration:

  • ZLIB library
  • LZMA library
  • ZSTD library
  • OPENSSL library (signature handling in modinfo)

Typical configuration and installation

meson setup builddir/
meson compile -C builddir/
sudo meson install -C builddir/

For end-user and distributions builds, it's recommended to use:

meson setup --buildtype release builddir/

Hacking

When working on kmod, use the included build-dev.ini file, as:

meson setup --native-file build-dev.ini builddir/

Make sure to read our contributing guide and the other READMEs: libkmod and testsuite.

Compatibility with module-init-tools

kmod replaced module-init-tools, which was EOL'ed in 2011. All the tools were rewritten on top of libkmod and they can be used as drop in replacements. Along the years there were a few behavior changes and new features implemented, following feedback from Linux kernel community and distros.
