Judging from the bind01 test case code, about the only useful
information available in this message,

https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/syscalls/bind/bind01.c

(and even that only indirectly), this ought the be error in the original
patch where -EEXIST from kern_path_create isn't translated to
-EADDRINUSE. This is fixed in the patch I sent yesterday, tested via
highly unsophisticated

perl -MSocket  <<'TT'
socket($sk, AF_UNIX, SOCK_DGRAM, 0);
bind($sk, sockaddr_un("."));
print "$!\n"
TT
