Hi Jeff,

It looks like it's fixed in the current kernel.

Hint: try grepping the package changelog:

$ rpm -q --changelog kernel-2.6.32-504.el6.x86_64 | grep sendfile
- [fs] Fix sendfile write-side file position (Steven Whitehouse) [770023]
- [fs] sendfile(): check f_op.splice_write() rather than f_op.sendpage()
(Lukas Czerner) [689426]

Those entries seem to match the bug description in the errata you list
so I'd guess it's fixed.
