Some user space tools need to identify SYSV shared memory when examining /proc/<pid>/maps. To do so they look for a block device with major zero, a dentry named SYSV<sysv key>, and having the minor of the internal sysv shared memory kernel mount. To help these tools and to make it easier for people just browsing /proc/<pid>/maps this patch modifies hugetlb sysv shared memory to use the SYSV<key> dentry naming convention. User space tools will still have to be aware that hugetlb sysv shared memory lives on a different internal kernel mount and so has a different block device minor number from the rest of sysv shared memory.
