From d4f510eb3f56d30dd1312fe902138c430db2b361 Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Fri, 6 May 2016 10:26:31 -0600 Subject: ide: Switch to byte-based aio block access Sector-based blk_aio_readv() and blk_aio_writev() should die; switch to byte-based blk_aio_preadv() and blk_aio_pwritev() instead. The patch had to touch multiple files at once, because dma_blk_io() takes pointers to the functions, and ide_issue_trim() piggybacks on the same interface (while ignoring offset under the hood).
