From 72c6e7afc43e19f68a31dea204fc366624d6eee9 Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Wed, 28 Mar 2012 18:41:22 +0100 Subject: [PATCH] dm crypt: add missing error handling Always set io->error to -EIO when an error is detected in dm-crypt. There were cases where an error code would be set only if we finish processing the last sector. If there were other encryption operations in flight, the error would be ignored and bio would be returned with success as if no error happened. This bug is present in kcryptd_crypt_write_convert, kcryptd_crypt_read_convert and kcryptd_async_done.
