Unable to build Linux kernel module for v4.15 #1

Open jserv opened 4 years ago

jserv commented 4 years ago

I managed to build sofa on Ubuntu Linux 18.04-LTS which is based on Linux kernel version 4.15. However, I failed to build Linux kernel module. Here are the instructions to reproduce:

cd src
sh build_sofa.sh

The build system complained as following:

sofa/src/storage_core/lfsm/common/mem_manager.c: In function 'init_memory_manager':
sofa/src/storage_core/lfsm/common/mem_manager.c:42:10: error: implicit declaration of function 'bioset_init'; did you mean 'bio_init'? [-Werror=implicit-function-declaration]
          bioset_init(&memMgr.bioset, bio_pool_size, 0,
          ^~~~~~~~~~~

ITRI-SOFA is developed and compiled on Centos 8 which is based on kernel 4.18. We did not run SOFA on Ubuntu. In the future we will support fedora and ubuntu platforms. On Fedora 29, we have verified that it is executable.

Linux 4.18 replaced bioset{create,free} with bioset{init,exit}. Check this patch for details: https://github.com/crawfxrd/dattobd/commit/c9e1e0117e8c1bd51a3cfe88701cb86573f30df9
