+Subject: dm crypt: Fix data corruption with dm-crypt over RAID5
+
+Fix corruption issue with dm-crypt on top of software raid5. Cancelled
+readahead bio's that report no error, just have BIO_UPTODATE cleared
+were reported as successful reads to the higher layers (and leaving
+random content in the buffer cache). Already fixed in 2.6.19.
