Subject: ipc: enable is_ns_init_id() assertions
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=3826d5dd06996007c13352b7fa65625ab570f651;p=thirdparty%2Flinux.git

ipc: enable is_ns_init_id() assertions

The ipc namespace may call put_ipc_ns() and get_ipc_ns() before it is
added to the namespace tree. Assign the id early like we do for a some
other namespaces.
