[Pvfs2-developers] readv/writev gone in 2.6.19-rc4

[Rob Ross]

the good news is that the new structure that they've added:
struct niovec
     {
         void __user *iov_base;
	__kernel_size_t iov_len;
	__kernel_loff_t iov_off; /* NEW */
     };

allows one to do a very limited version of list I/O through the kernel. 
minor step in the right direction.
