Update of /cvsroot/libsysio/libsysio/include
In directory sc8-pr-cvs1:/tmp/cvs-serv23555/include

Modified Files:
	sysio.h 
Log Message:


A roll-up patch from CFS (Eric Mei <er...@cl...>)

- intent.diff
   small changes on intent related behavior. I simply follow the lustre
   kernel code here.
     - open() need to pass down param 'flags'.
     - 'setattr' related syscalls, like chown/chmod/utime/..., don't need
       intent during path resolution.

- sockets.diff
   your socket driver.

- nativefs.diff
   only add fcntl code into native driver. not sure whether it's
   complete, but ok for current testing.

- trace.diff
   this patch add SYSIO_ENTER/SYSIO_LEAVE macros.
