[PATCH] fs: Add MODULE_SOFTDEP declarations for hard-coded crypto drivers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This helps initramfs builders and other tools to find the full
dependencies of a module.

Debian on powerpc (ppc32) still uses yaboot as default boot loader. Using a
default installation (debian-installer) 64bit and metadata_csum feature are
not setup in ext4. This is discussed in more details at:

https://bugs.debian.org/825110#81

and implemented here:

https://anonscm.debian.org/cgit/d-i/partman-ext3.git/patch/?id=f87dc92157262de1ad8dd3f2343436f08271b4dc

This means that building the kernel as default debian package:

  make ARCH=powerpc XYZ_defconfig
  make -j8 ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- bindeb-pkg

Will lead to the following boot failure (initramfs prompt):

  /dev/sda3: clean, 127679/305216 files, 11128559/1220703 blocks done.
  [    5.592819] EXT4-fs (sda3): Cannot load crc32c driver.
  mount: mounting /dev/sda3 on /root failed: No such file or directory
