When I moved the orphan adding to btrfs_truncate I missed the fact that during orphan cleanup we just add the orphan items to the orphan list without going through btrfs_orphan_add, which results in lots of warnings on mount if you have any orphan items that need to be truncated. Just remove this warning since it's ok, this will allow all of the normal space accounting take place.

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 and remounted it. I fix this by making sure to check and see if the current block group has a cluster and writing out any entries that are in the cluster to the cache, as well as writing any pinned extents we currently have to the cache since those will be available for us to use the next time the fs mounts. This patch also adds a check to the end of load_free_space_cache to make sure we got the right amount of free space cache, and if not make sure to clear the cache and re-cache the old fashioned way.

root_item->flags and root_item->byte_limit are not initialized when a subvolume is created. This bug is not revealed until we added readonly snapshot support - now you mount a btrfs filesystem and you may find the subvolumes in it are readonly. To work around this problem, we steal a bit from root_item->inode_item->flags, and use it to indicate if those fields have been properly initialized. When we read a tree root from disk, we check if the bit is set, and if not we'll set the flag and initialize the two fields of the root item.

the object id of the space cache inode's key is allocated from the relative root, just like the regular file. So we can't identify space cache inode by checking the object id of the inode's key, and we have to clear __GFP_FS flag at the time we look up the space cache inode.

Commit f23eb2b2 ('tty: stop using "delayed_work" in the tty layer') ended up causing hung machines on UP with no preemption, because the work routine to flip the buffer data to the ldisc would endlessly re-arm itself if the destination buffer had filled up. With the delayed work, that only caused a timer-driving polling of the tty state every timer tick, but without the delay we just ended up with basically a busy loop instead. Stop the insane polling, and instead make the code that opens up the receive room re-schedule the buffer flip work. That's what we should have been doing anyway. This same "poll for tty room" issue is almost certainly also the cause of excessive kworker activity when idle reported by Dave Jones, who also reported "flush_to_ldisc executing 2500 times a second" back in Nov 2010: http://lkml.org/lkml/2010/11/30/592 which is that silly flushing done every timer tick. Wasting both power and CPU for no good reason.
