Well, running 'mkfs.btrfs -O list-all' with 3.16 btrfs-progs gives the
following list of features:

device replace could fail due to another running scrub process, but this
failure doesn't get returned to userspace.
The following steps could reproduce this issue

This test is motivated by a bug found in btrfs when replaying a
directory from the fsync log. The issue was that if a directory
entry is both found in the persisted metadata and in the fsync
log, at log replay time the directory got set with a wrong i_size.
This had the consequence of not being

Nice. Sample output:

Hello Fellow Developers,
Today I ran the Xfs test suite on a test drive I have. Further moreI get a few
failing tests and will post the results of my run ofxfstests with ./check
below. If someone would like my local.conf for debugging purposes please let me
known.

Currently these macros just tie to assert(), which gives us line number and such

a backtrace so we can see how we got to the given assert. Thanks,

Asserting is no fun, we may be able to recover from this error in certain cases
(like btrfs-image and btrfsck). Just do what the kernel does and spit out an
error and return that there is only 1 copy. Thanks,

We use the read extent buffer infrastructure to read the super block when we are
creating a btrfs-image. This works out fine most of the time except when the fs
has been balanced, then it fails to map the super block. So we could fix
btrfs-image to read in the super in a special way, but thats
