generic_pipe_buf_steal — attempt to take ownership of a &pipe_buffer


int generic_pipe_buf_steal (struct pipe_inode_info * pipe,
 struct pipe_buffer * buf);


struct pipe_inode_info * pipe

the pipe that the buffer belongs to

struct pipe_buffer * buf

This function attempts to steal the struct page attached to buf. If successful, this function returns 0 and returns with the page locked. The caller may then reuse the page for whatever he wishes; the typical use is insertion into a different file page cache.
