ns: drop assert

2025-09-25T07:23:54Z

Otherwise we warn when e.g., no namespaces are configured but the initial namespace for is still around. Reviewed-by: Jan Kara Signed-off-by: Christian Brauner

ns: move ns type into struct ns_common

2025-09-25T07:23:54Z

It's misplaced in struct proc_ns_operations and ns->ops might be NULL if the namespace is compiled out but we still want to know the type of the namespace for the initial namespace struct. Reviewed-by: Jan Kara Signed-off-by: Christian Brauner

ns: add ns_debug()

2025-09-22T12:47:10Z

Add ns_debug() that asserts that the correct operations are used for the namespace type. Reviewed-by: Jan Kara Signed-off-by: Christian Brauner

ns: rename to __ns_ref

2025-09-19T14:22:38Z

Make it easier to grep and rename to ns_count. Reviewed-by: Jan Kara Signed-off-by: Christian Brauner

ns: add ns_common_free()

2025-09-19T14:22:36Z

And drop ns_free_inum(). Anything common that can be wasted centrally should be wasted in the new common helper. Reviewed-by: Jan Kara Signed-off-by: Christian Brauner

nscommon: simplify initialization

2025-09-19T12:26:19Z

There's a lot of information that namespace implementers don't need to know about at all. Encapsulate this all in the initialization helper. Reviewed-by: Jan Kara Signed-off-by: Christian Brauner

mnt: simplify ns_common_init() handling

2025-09-19T12:26:18Z

Assign the reserved MNT_NS_ANON_INO sentinel to anonymous mount namespaces and cleanup the initial mount ns allocation. This is just a preparatory patch and the ns->inum check in ns_common_init() will be dropped in the next patch. Reviewed-by: Jan Kara Signed-off-by: Christian Brauner

nscommon: move to separate file

2025-09-19T12:26:18Z

It's really awkward spilling the ns common infrastructure into multiple headers. Move it to a separate file. Reviewed-by: Jan Kara Signed-off-by: Christian Brauner
