While we have a transaction ongoing, the VM might decide at any time
to call btree_inode-i_mapping-a_ops-writepages(), which will start
writeback of dirty pages belonging to btree nodes/leafs. This call
might return an error or the writeback might finish with an error
before we attempt to commit

We use the read extent buffer infrastructure to read the super block when we are
creating a btrfs-image. This works out fine most of the time except when the fs
has been balanced, then it fails to map the super block. So we could fix
btrfs-image to read in the super in a special way, but thats

If you add a single 8GB tmpfs to a RAID1 btrfs
We check whether transid is already committed via last_trans_committed and
then search through trans_list for pending transactions. If
last_trans_committed is updated by btrfs_commit_transaction after we check
it (there is no locking), we will fail to find the committed transaction
and return

The RCU-friendy string API used internally by BTRFS is generic enough for
common use. This doesn't add any new functionality, but instead just moves the

This patch series makes the generic RCU string library used internally by BTRFS
accessible by anyone.
The first patch makes printk_ratelimited pass on the return value from printk.
Version 3 gives the temporary return variable a unique name to avoid name
clashes.
The second patch moves the RCU
printk returns an integer; there's no reason for printk_ratelimited to swallow
it.
