Changelog:
v3 - v4: Cleaning up commit message
Tests the noatime, relatime, strictatime and nodiratime mount options.
There is an extra check for Btrfs to ensure that the access time is
never updated on read-only subvolumes. (Regression test for bug fixed
with commit 93fd63c2f001ca6797c6b15b696a484b165b4800)

When trying to create a clone (reflink) of a file on a different device,
you'll get this error:
Invalid cross-device link
However, an empty file is created on the target location. An invalid
clone operation should not result in the creation of a file.
Example:
# mount
(...)
/dev/sdb1
All,
When adding a subvolume to a qgroup, pre-existing files in that
subvolume are not counted in the referenced/exclusive space of the
qgroup. Is this intended behavior ?
I create a subvol with one file:
# mkfs.btrfs /dev/sdg
# mount /dev/sdg /mnt/fulldisk
# cd /mnt/fulldisk
#
All,
The btrfs qgroup limit command has an option -c which means limit amount
of data after compression. Whether this option is specified or not, I seem
to be able to write more well-compressible data than the specified limit. I
was expecting that omitting the -c option would never allow me to
after enabling quota on a non-empty filesystem.

When data in a file is overwritten, starting somewhere in the middle of
the file, the overwritten space is counted twice against the space usage
numbers. Is this a bug, or did I something wrong?
This is what I did:
I create a subvolume and limit it to 4 MB, and create a 1000 KB file in
