+btrfs-inspect-internal - resolve different btrfs items for debug purpose
+'btrfs inspect-internal' <subcommand> <args>
+'btrfs inspect-internal' is used to resolve different items for debug purpose.
+'inode-resolve' [-v] <inode> <path>::
+Resolves an <inode> in subvolume <path> to all filesystem paths.
+verbose mode. print count of returned paths and ioctl() return value
+'logical-resolve' [-Pv] [-s bufsize] <logical> <path>::
+Resolves a <logical> address in the filesystem mounted at <path> to all inodes.
+By default, each inode is then resolved to a file system path (similar to the
+inode-resolve subcommand).
+skip the path resolving and print the inodes instead
+verbose mode. print count of returned paths and all ioctl() return values
+-s <bufsize>::::
+set inode container's size.
+This is used to increase inode container's size in case it is
+not enough to read all the resolved results. The max value one can set is 64k.
+'subvolid-resolve' <subvolid> <path>::
+Get file system paths for the given subvolume ID.
+'rootid' <path>::
+For a given file or directory, return the containing tree root id. For a
+subvolume return it's own tree id.
+The result is undefined for the so-called empty subvolumes (identified by inode number 2).
+'btrfs inspect-internal' returns a zero exist status if it succeeds. Non zero is
+returned in case of failure.
+'btrfs' is part of btrfs-progs. Btrfs filesystem is currently under heavy
+and not suitable for any uses other than benchmarking and review.
+Please refer to the btrfs wiki for
+further details.
