Cluster log daemon (clogd): use LVM bitops in place of ext2 bitops
...
Eliminate dependency on outside library, since the same functionality
exists in our tree.
[It is important that the bitops work in the same way, as the bitmaps
must remain backwards compatible. I haven't tested every architecture,
but the x86* archs work. My test involved using the old ext2fsprogs
bitops, memcpy'ing the bits over to the LVM bitset array and ensuring
that only the bits set via the old methods were set.]

Support crypt segment in libdevmapper tree.
...
- it can support multiple segments, but note that
to work properly, correct IV (initialization vector)
offset parameter must be set properly.
Because most usage of IV start offset is when we join
several crypto segments together (so iv_offset is the segment
start offset), DM_CRYPT_IV_DEFAULT is defined to simplify
the process.
Function accepts the string in cipher agrument (already
including chainmode and iv type; chainmode and iv parameters are NULL
in this case) or user can provide split parameters which will
join into dm-crypt cipher specification "cipher-chainmode-iv".
All these parameters must be supplied in correct dm-crypt format.

Use suspend with flush when device size was changed during table preload.
...
This allows online mirror resize, also removes condition to preventing
code to do this.
