[PATCH 0/4] xfs: fsstress/godown bug fixes

[Jeff Liu <jeff.liu@xxxxxxxxxx>]

Hi Folks,

I have observed another hang up when doing fsstress and shutting the file 
system.
The first two patches are manage to fix those issues, and the left are for code
clean ups.

Please note that, those patches are based on Christoph's previous fix:
[PATCH v2] xfs: remove xfsbdstrat error

I know that most of our folks are on vacation for the coming holidays, enjoy the
happy time, I just posted patches here. 


Thanks,
-Jeff
