Subject: [PATCH v2 00/26] kbuild: yet another series of cleanups (modpost and LTO)
Date: Sun,  1 May 2022 17:40:06 +0900	[thread overview]
Message-ID: <20220501084032.1025918-1-masahiroy@kernel.org> (raw)


This is the third batch of cleanups in this development cycle.

Major changes in v2:

 - V1 did not work with CONFIG_MODULE_REL_CRCS.
   I fixed this for v2.

 - Reflect some review comments in v1

 - Refactor the code more

 - Avoid too long argument error
