From cb66a7a1f149ff705fa37cad6d1252b046e0ad4f Mon Sep 17 00:00:00 2001 From: Al Viro Date: Tue, 4 Mar 2014 15:24:06 -0500 Subject: kill generic_segment_checks() all callers of ->aio_read() and ->aio_write() have iov/nr_segs already checked - generic_segment_checks() done after that is just an odd way to spell iov_length().
