Hello list,
I get constantly no space messages friends m btrfs on big volumes. Btrfs
balance always fixes it for 2-3 days. Now I'm in the process to recreate the
fs. Are there any options I could pass to mods.btrfs which help to prevent
this? Special use case heavy usage of cp reflink and modif

Hi
My btrfs-RAID6 seems to be broken again :(

Bio error reporting has been a mess for a while, and the increasing
use of chained bios makes it worse. Add a bi_error field to struct
bio to fix this.
Note that the rebase to 4.2-rc means a lot of context changes, so I've
dropped the Reviewed-by tags from V2 as it will need a re-review.

Reason:
Above code was wroten in 2012-08-01, together with

This patchset will add partial csum support for btrfs.
Partial csum will take full advantage of the 32 bytes csum space inside
the tree block, while still maintain backward compatibility on old
kernels.
