GENERIC_PIPE_BUF_MAP(9)		   pipes API	       GENERIC_PIPE_BUF_MAP(9)

NAME
       generic_pipe_buf_map - virtually map a pipe buffer

SYNOPSIS
       void * generic_pipe_buf_map(struct pipe_inode_info * pipe,
				   struct pipe_buffer * buf, int atomic);

ARGUMENTS
       pipe
	   the pipe that the buffer belongs to

       buf
	   the buffer that should be mapped

       atomic
	   whether to use an atomic map

DESCRIPTION
       This function returns a kernel virtual address mapping for the
       pipe_buffer passed in buf. If atomic is set, an atomic map is provided
       and the caller has to be careful not to fault before calling the unmap
       function.

       Note that this function calls kmap_atomic if atomic != 0.
