Hey, all. I'm dealing with a potentially flaky 3Ware controller. Got
seven 2 TB disks in a RAID-6. The BTRFS partition is a 9 TB partition.
I've had to do a couple hard shutdowns on the system, and now I'm getting
sporadic "Failed to read block groups" errors in dmesg:

Hi Miao,
The HEAD of the perf-improve fails to boot on my virtual machine.
The system calls btrfs_delete_delayed_dir_index() with trans block_rsv set to
NULL,
thus selects, in get_block_rsv(), empty_block_rsv whose reserve is 0 (and size
is also 0),
which leads to ENOSPC. I wonder below patch
