While adding tracepoint for btrfs, I got a problem:
btrfs uses some macros with ULL type, but tracepoint's macros,
__print_[flags,symbols](), only have unsigned long, so on 32bit box
there will be 64-32 truncate WARNINGs when compiling.
Here I'm inclined to make the replacement to clear those

This function call can be replaced by block_group-free_space, so
we don't have to iterate the tree.
(This function gets removed in my patchset for inode number caching)

Hallo, Struan,
Du meintest am 01.04.11:
1) Is the balancing operation expected to take many hours (or days?)
on a filesystem such as this? Or are there known issues with the
algorithm that are yet to be addressed?
May be. Balancing about 15 GByte needed about 2 hours (or less),

I noticed a huge problem with the free space cache that was presenting as an
early ENOSPC. Turns out when writing the free space cache out I forgot to take
into account pinned extents and more importantly clusters. This would result in
us leaking free space everytime we unmounted the filesystem

Hello all,
I've been trying to use btrfs with a very specific purpose during my MSc
thesis, and now I would very much appreciate any comments you may have on a
given issue.
Currently I'm trying to mask accesses to different snapshots by different
processes, while still using the same FS entry

Hi,
I have put a linux system on an external SSD recently, using btrfs for both
root (/) and /home. After a couple of hibernation cycles the system got stuck
and I had to reboot it ignoring the memory image on disk. Unfortunately, even a
normal reboot did not work anymore. The kernel

My fs is also broken this way, though for me it happened after
resizing the fs and then partition. I still need to go back to the
list thread and do some work on my image.
