If we change our default subvolume, btrfs receive will fail to find
subvolume. To fix this problem, we have three ideas:
1.make btrfs snapshot ioctl support passing source subvolume's objectid.
2.when we want to using interval subvolume path, we mount it other place
that use subvolume 5 as its

In order to improve the performance of fsync, we use the outstanding
ordered extents to avoid looking up the checksum from the csum tree.
But we didn't filter out the ordered extents whose csum is still being
calculated, when we got those ordered extents, we had to wait for the
csum calculation.

Hi,
please queue the following patches to 3.12 stable. They fix a few
crashes or lockups that were reported by users.
The patch stop using vfs_read in send may seem big for stable, but without it
the send/receive ioctl hits the global open file limit sooner or later,
depending on the ram size.
I've recently setup a system (Kernel 3.12.5-1-ARCH) which is layered as follows:
/dev/sdb3 - cache0 (80 GB Intel SSD)
/dev/sdc1 - backing device (2 TB WD HDD)
sdb3+sdc1 = /dev/bcache0
On /dev/bcache0, there's a btrfs filesystem with 2 subvolumes, mounted
as / and /home. What's been bothering me
Hello!
I have noticed that there have been important fixes for btrfs in the
mainline Linux git repository. However, there is just one btrfs fix
in Linux 3.12.5 after 3.12.
I think it's important to submit all serious bugfixes to the stable
kernels. It would protect users against data

qgroups need to have a consistent view of the references for a particular extent

this is no longer acceptable. So instead introduce lock_ref/unlock_ref. This
