2.6.18-stable review patch. If anyone has any objections, please let us know.
------------------
From: Christophe Saout <[email protected]>
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.
