Subject: [PATCH v2 0/2] Minor namespace code simplication
Date: Thu, 8 May 2025 14:49:28 -0400 [thread overview]
Message-ID: <20250508184930.183040-1-jsavitz@redhat.com> (raw)
The two patches are independent of each other. The first patch removes
unnecssary NULL guards from free_nsproxy() and create_new_namespaces()
in line with other usage of the put_*_ns() call sites. The second patch
slightly reduces the size of the kernel when CONFIG_CGROUPS is not
selected.
Joel Savitz (2):
kernel/nsproxy: remove unnecessary guards
include/cgroup: separate {get,put}_cgroup_ns no-op case
Changes from v1:
- now removing the guards instead of adding them where missing since
checking that all calls in the NULL case were already no-ops
- added second patch
include/linux/cgroup.h | 26 ++++++++++++++------------
kernel/nsproxy.c | 30 ++++++++++--------------------
