[lvm-devel] [PATCH] update support for cciss controller(s)

[Mike Snitzer]

The cciss driver calls register_blkdev() for each controller in the
system.  The first 8 cciss controllers are given a fixed major
(COMPAQ_CISS_MAJOR + i) and a name of: cciss%d

cciss controllers >8 get a dynamic major number.

Each controller supports a maximum of 16 partitions.

Update lvm's filtering to properly support the cciss controller (I left
"cciss" for compatibility's sake).

(This enables dracut to drop its, incorrect, "cciss0" 'types' entry).
