Hi,
This patch removes the ->sendfile() hook from the file_operations
structure, and replaces the sys_sendfile() mechanism to be based on
->splice_read() instead. There should be no functional changes.
- retval = in_file->f_op->sendfile(in_file, ppos, count, file_send_actor, out_file);
+ fl = 0;
+ if (in_file->f_flags & O_NONBLOCK)
+ fl = SPLICE_F_NONBLOCK;
+
+ retval = do_splice_direct(in_file, ppos, out_file, count, fl);
I like this, but are you sure it wont break user land ?
Some applications might react badly if sendfile() returns EAGAIN ?
