Subject: [PATCH 0/5] kernel: Standardize task comm setup for kthreads
Date: Sun, 12 Feb 2023 19:00:15 -0600	[thread overview]
Message-ID: <20230213010020.1813-1-michael.christie@oracle.com> (raw)

The following patches were made over Linus's tree. They standardize the
task->comm initialization. Currently, kthreads will set it up after a
successful kthread_thread call in the calling function. io_uring will
set it from the thread fn. And the vhost task patches added it's own
helper.

This patchset adds a new kernel clone args callout, setup_thread_fn,
which can be used to setup an internal struct, like is needed by
kthreads, and can also be used to set the task->comm like is needed
by kthread, io_uring and vhost.

Note that I have not yet compile tested all the archs in the first
patch. I was not sure if Linus was going to prefer this patchset's
approach to setting the comm or would like to leave it as it is now.
So this more of a RFC.
