Took longer than I hoped... Anyway, here's the current variant;
it's 5.11-based, lives in
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git misc.af_unix
Shortlog:
Al Viro (8):
af_unix: take address assignment/hash insertion into a new helper
unix_bind(): allocate addr earlier
unix_bind(): separate BSD and abstract cases
unix_bind(): take BSD and abstract address cases into new helpers
fold unix_mknod() into unix_bind_bsd()
unix_bind_bsd(): move done_path_create() call after dealing with ->bindlock
unix_bind_bsd(): unlink if we fail after successful mknod
__unix_find_socket_byname(): don't pass hash and type separately

The actual fix is in #7/8, the first 6 are massage in preparation to that
and #8/8 is a minor followup cleanup. Individual patches in followups.
Please, review.
