If we runt the direct IO, we should not run auto defrag, because it may
introduce buffered IO vs direcIO problem, and make direct IO slow down.

Steps to reproduce:
# mkfs.btrfs disk
# mount disk mnt
# dd if=/dev/zero of=mnt/file bs=512 seek=5 count=8

# umount mnt
# dmesg
WARNING: at fs/btrfs/inode.c:7140
Since we can pre-allocate the space past EOF, we should be able to reclaim
that space if we need. This patch implements it by removing the EOF check.
Though the manual of fallocate command says we can use truncate command to
reclaim the pre-allocated space which past EOF, but because truncate
ret variant may be set to 0 if we read page successfully, but it might be
released before we lock it again. On this case, if we fail to allocate a
new page, we will return 0, it is wrong, fix it.

I reported this issue a while ago:

when I was testing what I thought might be
My previous reply was incorrect in one point - the data is never copied from
the transaction log into the sparse datafiles, instead the application writes
the same data independently to both locations.
Also, I failed to mention that the files are memmapped, and it's possible that

Dear all,
thanks for developing btrfsck!
Now, I'd like to contribute -as far as I can. I'm not a developer, but I
do have some linux-experience.
I've been using btrfsck on two 3TB HDDs (mirrored) for a while now under
Kernel 3.0. Now it's corrupt. I had some hard resets of the machine

Maybe you can use systemtap to track what's going on.

Hi everyone, I'm running btrfs since octobre 2012 and I would like to
understand 2 behavior that I noticed.
1. When I delete a big directory, sometimes it can hang my box for 1
