Comment 2 Dave Chinner 2011-01-13 01:10:56 EST

The upstream patch series has too many dependencies to apply to a RHEL 6 tree easily, so I'm going to port only the first and last patches of the series and ignore all the clean-ups. The first patch fixes sync write error return values, the last patch fixes the unaligned dio issue.

Comment 3 Eric Sandeen 2011-01-13 17:11:09 EST

Dave, if you can make this one for 6.1, can you set devel_ack?  thanks.
