Couldn't btrfs.wiki.kernel.org be made a CNAME for btrfs.ipv5.de for the
time being until kernel.org is up and running?
Or alternatively all requests

Dear devs,
My filesystem is super-sluggish since about a week, and perf top tells me
that find_next_bit(), find_next_zero_bit() is eating my netbook's CPU.
The kernel is 3.3-rc3+188 (g3ec1e88) and I don't use this laptop a lot,
so I'm ready to cooperate.

So, the btrfs-convert for the smaller drive is done... after near 5
days. Which stats can I give you ?
It's a 340GB LVM block device, and btrfs filesystem df /backup/ say that :
Data: total=225.97GB, used=181.94GB
System: total=32.00MB, used=24.00KB
Metadata: total=111.00GB, used=91.56GB

What happened to the patches to --help and man pages that did explain the

Normally I just toss patches into git, but this one is pretty subtle and

[Referring to https://lkml.org/lkml/2012/1/17/381], and perhaps I'm a bit
previous, but what are the command sequence to change the raid levels?
Wouldn't mind being pointed to git manual if better for you.
Well done and thank you to all involved.

btrfs_iget() never return NULL. So, NULL check is unnecessary.

The right option is 'o' not 'c'. And this tool is used for the block devices
on which there is a btrfs file system, so change mount_point to device.

If the fs/file tree is not the parent of the snapshot, it is reasonable
that we can not find the relative reference and back reference. But btrfsck
doesn't consider this case, and reports unresolved refs message, it's wrong,
fix it.
