Subject: [PATCH v2 00/11] Introduce kernel_clone(), kill _do_fork()
Date: Wed, 19 Aug 2020 12:46:44 +0200 [thread overview]
Message-ID: <20200819104655.436656-1-christian.brauner@ubuntu.com> (raw)
Hey everyone,
This is a follow-up to the fork-related cleanup. It's based on a brief
discussion after the initial series was merged.
Last cycle we removed copy_thread_tls() and the associated Kconfig
option for each architecture. Now we are only left with copy_thread().
Part of this work was removing the old do_fork() legacy clone()-style
calling convention in favor of the new struct kernel_clone args calling
convention.
The only remaining function callable outside of kernel/fork.c is
_do_fork(). It doesn't really follow the naming of kernel-internal
syscall helpers as Christoph righly pointed out. Switch all callers and
references to kernel_clone() and remove _do_fork() once and for all also
switching the return value for kernel_clone() from long to pid_t since
that's what we use in all other places where we're dealing with process
identifiers.
For all architectures I have done a full git rebase v5.9-rc1 -x "make
-j31". There were no built failures and the changes were fairly
mechanical.
The only helpers we have left now are kernel_thread() and kernel_clone()
where kernel_thread() just calls kernel_clone().
Thanks!
Christian
