[PATCH v2 1/2] xfs_io: add missed inode command into man page

[Zorro Lang <zlang@redhat.com>]

There's an "inode" command in xfs_io, it's used to query physical
information about an inode. But there's not any information about
it in xfs_io and other related man pages. So document this command
in the xfs_io man page now.

Hi,

This V2 follow Eric's suggestion, changed some description, and moved
the inode command from "FILE I/O" section to "OTHER COMMANDS" section.

Thanks,
Zorro

+The inode command queries physical information about an inode. With
+no arguments, it will return 1 or 0, indicating whether or not if any
+inode numbers greater than 32 bits are currently in use in the filesystem.
+If given an inode
+.I number
+as an argument, then inode command will return this inode
+.I number
+if it's in use, or 0 if not. With
+.BI \-n " number"
+, the next used inode number after this
+.I number
+will be returned, or 0 if can't find the next one. With
+.B \-v
+the command will also report the number of bits (32 or 64) used by the
+inode
+.I number
+printed in the result; if no inode
+.I number
+was specified on the commandline, the maximum possible inode number in
+the system will be printed along with its size.
