Hello,
I''m seeing a lot of warnings in dmesg with a BTRFS filesystem. I''m using
the 3.1 kernel, I found a patch for these warnings (

<http://marc.info/?l=linux-btrfs&m=131547325515336&w=2>, but that patch
has already been included in 3.1. Are there any other patches I can try?

[patch 00/65] Error handling patchset v3
Hi all -
Here''s my current error handling patchset, against 3.1-rc8. Almost all of
this patchset is preparing for actual error handling. Before we start in
on that work, I''m trying to reduce the surface we need to worry about. It
turns out that there is a ton of code that returns an error code but never
actually reports an error.
The patchset has grown to 65 patches. 46 of them

[PATCH v0 00/18] btfs: Subvolume Quota Groups
This is a first draft of a subvolume quota implementation. It is possible
to limit subvolumes and any group of subvolumes and also to track the amount
of space that will get freed when deleting snapshots.
The current version is functionally incomplete, with the main missing feature
being the initial scan and rescan of an existing filesystem.
I put some effort into writing an introduction into
