[PATCH 0/9] btrfs: Fix no_space on dd and rm loop

[Zhaolei <zhaolei@cn.fujitsu.com>]

From: Zhao Lei <zhaolei@cn.fujitsu.com>

I resend this patch set with some changes:
1: Move a cleanup patch for btrfs_check_data_free_space() into
2: Rebased on top of v4.0-rc5
3: Fixed a lock problem reported by:
   'Tsutomu Itoh' <t-itoh@jp.fujitsu.com>

Tested by busy dd and rm loop script in 2000 times.
Confirmed having-problem in v4.0-rc5 and no-problem on top of
this patchset.

I'll add xfstests for this case later.

This is available at fix_no_space branch on my tree:
  git://github.com/zhaoleidd/btrfs.git
It is also included in integration-for-chris branch in above tree.

Thanks
Zhaolei
