From ee84a3032b74055feed192a727e872b0a18d1140 Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Thu, 8 Jun 2023 16:28:00 -0700 Subject: perf thread: Add accessor functions for thread Using accessors will make it easier to add reference count checking in later patches. Committer notes: thread->nsinfo wasn't wrapped as it is used together with nsinfo__zput(), where does a trick to set the field with a refcount being dropped to NULL, and that doesn't work well with using thread__nsinfo(thread), that loses the &thread->nsinfo pointer. When refcount checking is added to 'struct thread', later in this series, nsinfo__zput(RC_CHK_ACCESS(thread)->nsinfo) will be used to check the thread pointer.
