hi,
i'm working on an initrd hook
[http://aur.archlinux.org/packages.php?ID=33376] to support
non-volatile system rollbacks (promoting a temporary rollback snapshot
to the new active/default). when the system is installed to the
default/. subvolume (as many users probably initially do), it is
Hi all,
Over the past few months, I've been trying out btrfs on separate mountpoints.
I like it very much so I would like to try it on my home or root
volumes and see if I can do something fun with the snapshots.
As btrfs still isn't production-ready, I made sure everything is
backed-up to an
Hi,
moving along to a question... can the default subvolume be
swapped/removed/renamed/popped/shifted?
I think btrfs subvolume list; btrfs subvolume set-default id path
does what you need.

-Use iov_iter_count() instead of count in a few places

In order for AIO to work, we need to implement aio_write. This patch converts
our btrfs_file_write to btrfs_aio_write. I've tested this with xfstests

Hi,
When we tested btrfs with Josef's test-tools, a FAIL

After looking into it, we found that aops-bmap had
been deleted because btrfs's COW + swapfile led to
corruption.
So, is there a plan for this bmap operation?
