[PATCH] stat,tail: recognize new FS types: bdevfs, inodefs, qnx6

[Jim Meyering]

Going through the coreutils README-release procedure,
I ran "make -C src fs-magic-compare" on my handy Fedora rawhide VM,
and it printed these new symbol names:

# define S_MAGIC_BDEVFS 0x62646576
# define S_MAGIC_BINFMTFS 0x42494E4D
# define S_MAGIC_MTD_INODE_FS 0x11307854
# define S_MAGIC_QNX6 0x68191122

One is just a renaming, but the other three are indeed new.
Well, they're new names, at least.

The linux kernel folks recently gave names in their magic.h to
these previously-open-coded literal hexadecimal strings.

Seeing QNX4 and QNX6, I wondered if there were a well known magic number
for a QNX5 file system type, but a few quick searches suggest not.

Subject: [PATCH] stat,tail: recognize new FS types: bdevfs, inodefs, qnx6

* src/stat.c (human_fstype) [__linux__]: Add 'case's for these local
file system types: bdevfs (0x62646576), inodefs (0x42494E4D),
qnx6 (0x68191122).
Now that the kernel has a name for S_MAGIC_BINFMTFS, use
theirs in place of our S_MAGIC_BINFMT_MISC.
* NEWS (New features): Mention it.
