We don't have to keep subvolume's block_rsv during transaction commit,
and within transaction commit, we may also need the free space reclaimed
from this block_rsv to process delayed refs.

Thank you Chris.

Hi Felix,
It seems some reported this problem before. The problem for your below case
is because you use latest btrfs-progs(v3.12?), which will need kernel
update,
kernel 3.12 is ok.
However, i think btrfs-progs should keep compatibility, i will send a
patch to
make things more friendly.

Hi List,
My backup stopped working and I can't figure out why. I'm using
send/receive with the "-p" switch for incremental backups using the
last snapshot as a parent snapshot for sending only the changed data.
The problem occurs using my own backup script. After I discovered the

The patch below is a simple quick attempt at allowing the filesystem
UUID to be specified by the user at mkfs time. Googling around I've
seen a lot of people wishing they could "change their btrfs uuid".
I understand why that's not going to happen. But this little patch
seems like it could give t

Hello All,
I had some random corruption issues when I run some serious IOs with
these patches.
Found out that the function clean_tree_block() is the problem.
IIUC, this function is used to drop a dirty extent buffer when it is not
needed any more to be written to the disk.
In my case, the exten

This is my recent change to avoid memory leak in bio_endio. But I
think the problem is higher up, most likely bio_endio is called twice
