Hi,
The moment I define a new variable under thread_options I start seeing a crash in 'setup_files' files
Function. Backtrace points to the following lline:
if (td->io_ops->setup). Gdb shows the value of null for io_ops.
So essentially what's happenings is io_ops is not getting set correctly when I add a new
variable under 'thread_options' structures.
This can be easily reproduced by simply adding a variable under thread_options structiure.
No other changes are required. Can someone help?

Might be a build issue, try to do a make clean after modifying the
header.
