Just for performance tests I run:

use_block_rsv()
ret = block_rsv_use_bytes(block_rsv, blocksize);
if (!ret)
return block_rsv;
if (ret) {
WARN_ON(1);
ret = reserve_metadata_bytes(trans, root, block_rsv, blocksize,
Why is there a WARN_ON(1)? Running the bonnie benchmark is basically impossible
that.
This is being worked on, if you really don't like it pull my git tree
and test it out and see if the errors go away
git://git.kernel.org/pub/scm/linux/kernel/git/josef/btrfs-work.git
Do you plan to fix it for 3.1? If not, any chance to at least update it
to WARN_ON_ONCE?
Thanks,
Bernd
