Subject: dm-crypt: add cond_resched() to crypt_convert()
From: Milan Broz <mbroz@xxxxxxxxxx>
Add cond_resched() to prevent monopolising CPU when processing large bios.
dm-crypt processes encryption of bios in sector units. If the bio request
is big it can spend a long time in the encryption call.
(akpm: needed in 2.6.26 and, given that it fixes soft-lockup warnings,
needed in -stable too)
