The branch stable/13 has been updated by wulf: URL: https://cgit.FreeBSD.org/src/commit/?id=4fba1853b5bdb427912acda92357d041d9a13d7e commit 4fba1853b5bdb427912acda92357d041d9a13d7e Author: Vladimir Kondratyev <wulf@FreeBSD.org> AuthorDate: 2021-09-29 20:13:53 +0000 Commit: Vladimir Kondratyev <wulf@FreeBSD.org> CommitDate: 2021-10-13 09:02:17 +0000 LinuxKPI: stub anon_inode_getfile Although drm-kmod contains better implementation which is able to allocate real entries on pseudofs, this feature has never been used. Starting from drm-kmod v5.6 old implementation began to leak entries on each drm device close(). Now just drop pseudofs support instead of fixing it in drm-kmod and provide stub in base.
