When building on ppc64 I hit a number of warnings in printf:
btrfs-map-logical.c:69: error: format ‘%Lu’ expects type ‘long long
unsigned int’, but argument 4 has type ‘u64’
Fix them.

Hi Chris,
below is enclosed a trivial patch, which has the aim to improve the error
reporting of the "btrfs" command.
You can pull from
http://cassiopea.homelinux.net/git/btrfs-progs-unstable.git
branch
strerror
I changed every printf("some-error") to something like:
e = errno;
fprintf(stderr, "ERROR: .... - %s", strerror(e));
so:
1) all the error are reported to standard error
2) At the end of the message is printed the error as returned by the system.
The change is quite simple, I replaced every printf("some-error") to the line
above. I don't touched anything other.
I also integrated a missing "printf" on the basis of the Ben patch.
This patch leads the btrfs command to be more "user friendly" :-)
Regards
G.Baroncelli

If we meet a bad extent type, find_updated_files is going
to print random things. Better warn the user about what
happens.
This fixes:

When we compile btrfs-progs in RHEL5(with default gcc version 4.1.2 20070626),
we can get following error:
cc1: warnings being treated as errors

These varient are always initialized except inconsistent data in file system.
We can set initial value for these variant for this situation.

btrfs-subvol find-new <subvol> <id> will search through a given subvol
and print out all the files with extents newer than a given id.
Care must be taken to make sure any pending delalloc is on disk before
running this because that won't show up in the output.
This commit introduces a new command called 'btrfs' for managing
a btrfs filesystem. 'btrfs' handles:
- snapshot/subvolume creation
- adding/removal of volume (ie: disk)
- defragment of a tree
- scan of a device searching a btrfs filesystem
- re-balancing of the chunk on the disks
- listing subvolumes and snapshots
This has also been updated to include the new defrag range ioctl.
