Sorry about this, it's an overly verbose sanity check that I put in
when we were having problems with xfs writing misaligned blocks. I've
knocked it out of the latest bitkeeper repository:
bk://device-mapper.bkbits.net/2.4-stable
cvs will get updated at some point.
Alternatively just knock out this if statement from dm.c:
/*
* Sanity checks.
*/
if (bh->b_size > block_size)
DMERR("request is larger than block size "
"b_size (%d), block size (%d)",
bh->b_size, block_size);
If you are using xfs please be aware that you will need to use the new
journal log format to avoid misalignment problems (search this list
for previous posts).
