[PATCH 1/4] Btrfs: map the node block when looking for readahead targets
If we have particularly full nodes, we could call btrfs_node_blockptr up to 32
times, which is 32 pairs of kmap/kunmap, which _sucks_. So go ahead and map the
extent buffer while we look for readahead targets. Thanks,

State of nocow file attribute
Hello,
some time ago we discussed on #btrfs that the nocow attribute for files wasn''t
working (around 3.3 or 3.4 kernels). That was evident by files fragmenting even
with the attribute set.
Chris mentioned to find a fix quickly for that, and posted some lines of change
into irc. But recently someone mentioned that 3.6-rc looks like still not
respecting nocow for files.
Is there really

Mknod: Operation not permitted
When trying to move my root to a btrfs filesystem, I found a missing
feature (or a bug). It's not possible to create device files. To
reproduce, run this on a btrfs filesystem:
mknod test c 1 1
result:
mknod: `test': Operation not permitted

[BUG?] There is a possibility that 'i_ino' overflows
Hi,
In btrfs, inode number is increased each time a new file or directory
is made.
Therefore, if the making deletion of the file is repeated, value of
''i_ino'' increases rapidly.
For example, inode number changes as follows.
$ touch foo
$ ls -i foo
266 foo
$ rm foo
$ touch bar
$ ls -i bar
267 bar
$
And then, length of ''i_ino'' and
