Subject: [PATCH v2 0/5] userfaultfd/selftests: A few cleanups
Date: Mon, 12 Apr 2021 19:27:48 -0400 [thread overview]
Message-ID: <20210412232753.1012412-1-peterx@redhat.com> (raw)
v2:
- rebase to v5.12-rc7-mmots-2021-04-11-20-49
- collect r-bs from Axel
I wanted to cleanup userfaultfd.c fault handling for a long time. If it's not
cleaned, when the new code grows the file it'll also grow the size that needs
to be cleaned... This is my attempt to cleanup the userfaultfd selftest on
fault handling, to use an err() macro instead of either fprintf() or perror()
then another exit() call.
The huge cleanup is done in the last patch. The first 4 patches are some other
standalone cleanups for the same file, so I put them together.
Please review, thanks.
Peter Xu (5):
userfaultfd/selftests: Use user mode only
userfaultfd/selftests: Remove the time() check on delayed uffd
userfaultfd/selftests: Dropping VERIFY check in locking_thread
userfaultfd/selftests: Only dump counts if mode enabled
userfaultfd/selftests: Unify error handling
