Core dump ignores facl (setfacl) in RHEL

I had been tasked with figuring out how to have an environment that would allow multiple users to access core files.  I thought: simple enough, I'll just have to mess around with the facl for the directory, specifically the "default" entry.

Well, I was wrong.  I had attempted:
# remount filesystem and enable acl
chmod 775 /u01/core
chmod g+s /u01/core
chgrp smsvcs /u01/core
setfacl -m g::rwx,o:rwx,d:o::r-x /u01/core

It turns out that the coredump function (do_coredump) creates the file 0600

int do_coredump(long signr, struct pt_regs * regs)
 {
         struct linux_binfmt * binfmt;
         char corename[6+sizeof(current->comm)];
         struct file * file;
         struct inode * inode;
 
         lock_kernel();
         binfmt = current->binfmt;
         if (!binfmt || !binfmt->core_dump)
                 goto fail;
         if (!current->dumpable || atomic_read(&current->mm->mm_users) != 1)
                 goto fail;
         current->dumpable = 0;
         if (current->rlim[RLIMIT_CORE].rlim_cur < binfmt->min_coredump)
                 goto fail;
 
         memcpy(corename,"core.", 5);
 #if 0
         memcpy(corename+5,current->comm,sizeof(current->comm));
 #else
         corename[4] = '\0';
 #endif
         file = filp_open(corename, O_CREAT | 2 | O_TRUNC | O_NOFOLLOW, 0600);
         if (IS_ERR(file))
                 goto fail;
         inode = file->f_dentry->d_inode;
         if (inode->i_nlink > 1)
                 goto close_fail;        /* multiple links - don't dump */
 
         if (!S_ISREG(inode->i_mode))
                 goto close_fail;
         if (!file->f_op)
                 goto close_fail;
         if (!file->f_op->write)
                 goto close_fail;
         if (!binfmt->core_dump(signr, regs, file))
                 goto close_fail;
         unlock_kernel();
         filp_close(file, NULL);
         return 1;
 
 close_fail:
         filp_close(file, NULL);
 fail:
         unlock_kernel();
         return 0;
 }
