3943b040f1 bcache: release dc->writeback_lock properly in bch_writeback_thread()
The writeback thread would exit with a lock held when the cache device
is detached via sysfs interface, fix it by releasing the held lock
before exiting the while-loop.

d23599630b bcache: use routines from lib/crc64.c for CRC64 calculation
Now we have crc64 calculation in lib/crc64.c, it is unnecessary for
bcache to use its own version.  This patch changes bcache code to use
crc64 routines in lib/crc64.c.

bc9e9cf040 dm crypt: don't decrease device limits
dm-crypt should only increase device limits, it should not decrease them.

This fixes a bug where the user could creates a crypt device with 1024
sector size on the top of scsi device that had 4096 logical block size.
The limit 4096 would be lost and the user could incorrectly send
1024-I/Os to the crypt device.
