mainline inclusion from mainline-5.11-rc1 commit 71ccb50074f31a50a1da4c1d8306d54da0907b00 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I5EUVD CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
-------------------------------------------------
For consistency of output, emit "name <anon>" for BTFs without the name. This keeps output more consistent and obvious.
